refactor(web): remove --dev; mount the reload chain unconditionally

The client-hmr row joins the web bundle as an ordinary always-on roster
row: without a rebuild watcher rewriting client bundles it polls
unchanged files and stays idle. This deletes the --dev flag, the web
runtime's mode config, the mode-forked prompt contract, the DSH_WEB_MODE
bash variable, and the post-settlement row-creation machinery the
conditional row required. dsh web + pnpm run dev:web remains the
development loop.

A roster row that fails to import is caught by `assertEntriesLoaded`; a row whose fiber rejects is reported with its original stack by `assertEntriesActivated` ([host boot decision](2026-07-24-web-config-tree-boot-and-transport-layering.md)).

2. The `dsh-client-modules` node half (the package is dual-face: its browser half is the module table) scans loader entries' package.json `dsh.client` declarations and composes `window.__DSH_BOOT__`: `{ rev, entries: [{ id, url, rev, inject?, immediately? }] }`. The `inject` edges and the `immediately` mark come from manifests, never hand-copied. It refuses declared plugins without built `./client` bundles and groups their package/path rows under one required source-build instruction; malformed declaration fields also fail activation, and the host audit reports either error from the FAILED fiber.
3. Scanning is incremental per package — there is no full-rescan code path. Each cordis `internal/plugin` emission marks the fiber's entry name dirty (entry-less fibers drop O(1)); a microtask flush reconciles each dirty name against live loader entries, with package metadata (including the negative "not a client package" verdict) cached per name forever and bundle re-hashing reachable only through `rebuilt(id)`. The activation pass seeds the same dirty set from current entries and flushes synchronously, so first scan and steady state share one implementation. Each bundle's content hash is its `rev` (cache busting + HMR diff anchor), the row set hashes into `graph.rev`, and every row is served as a script resource at `/plugins/<id>/client.js?rev=…`, with its source map at the same path plus `.map`.

### Hot reload: one driver plugin, self-watched bundles
Whether hot reload is active is a composition decision: dev compositions mount the `client-hmr` row (a normal plugin package, appended by `--dev`) whose node half brings the bundle watch and the SSE channel; prod compositions mount nothing and have neither.
Hot reload is a composition decision: the web bundle mounts the `client-hmr` row (a normal plugin package) unconditionally; its node half brings the bundle watch and the SSE channel, and the chain stays idle until a rebuild watcher rewrites client bundles. A composition that must not expose it disables the row.
How does a rebuilt bundle become a reload signal? The hmr node half observes it itself — no builder tells it. It reads bundle paths from `ctx.clientModuleHost.clientPath(id)`, and one HMR-owned interval stat-polls every current graph row. Adding a row is ordered as synchronous stat baseline, then immediate `clientModuleHost.rebuilt(id)`: a write after the module host's graph hash but before that baseline is caught by the immediate re-hash, while a write after the baseline leaves a stat delta for the next poll. This avoids `fs.watchFile`, whose asynchronous first baseline can silently absorb a construction-time rebuild. Watch membership follows `onGraphChanged`; vanished rows drop out, and a bundle missing at poll time keeps its row dirty so reappearance forces a re-hash even with identical metadata. On a mtime/size delta or dirty row, `clientModuleHost.rebuilt(id)` is the single re-hash entry point; when the `rev` actually changed, the node half broadcasts a `rebuilt` frame on `GET /plugins/events` — a system SSE channel that sends the full graph on connect and `rebuilt` frames on change, presentation-only wire that never enters the session log. Polling is deliberate because inotify does not fire on the weka network mount, the same reason the build-side watcher needs `--poll`; the interval is a validated config field (default 500ms), and disposal clears the one timer. Rebuilding bundles is any tsdown watch process's business — `scripts/dev-web.ts` remains the watch-build entry point, discovering its package list through `dsh.client` while scanning `packages/*/*/package.json` at startup — and builder and host share zero protocol. A torn read self-heals: stats keep changing while the write completes, so the next poll re-hashes and broadcasts the final rev.

Plugin packages have one shape, so the purity gate covers them all. Dependency edges and the boot tier live with their owners — the manifests — while the composing app holds only the roster and the `--dev` switch. The drift classes stay structurally closed: share-list hand-sync, load-order coupling, cross-plugin imports, roster/tier double bookkeeping. Browser-native script loading preserves the standard mapping among plugin network resources, generated bundles, and TypeScript/TSX sources, while the module system keeps only one replaceable `loadBundle` hook.

Include keeps nested row expressions raw until their target row reaches this point. `--help` leaves the provider's service absent, so dependent rows never activate, and a live patch reload interpolates again against the service that remains active, so a served port cannot be silently reset.

Two further consequences. Loader mounts sibling rows concurrently, so one row can activate while another still mounts or while the whole boot is rolling back; the Web bundle therefore publishes its URL only after its own Loader tree settles. The Web bundle's runtime plugin owns the harness-source prompt section too, so `dsh web` and `dsh --profile web` boot identically without Web-specific launcher setup.
## Why Loader owns the ordering
Four framework facts shape the mechanism:
Three framework facts shape the mechanism:
- **A profile's rows arrive inside the root include's `patches` option.** Include declares the `EntryGroup.key` tree-carrier marker (as Group does), so Loader keeps its config — entry and patch lists, including Include's own `path` — literal instead of recursively evaluating nested `!!js` nodes in the Include context; each expression resolves in its target row's fiber.
- **Cordis activates a fiber only after all declared injections are active.** Immediately before each activation, Cordis runs the `internal/config` waterfall against the fiber's own context; Loader's listener interpolates the raw config after Cordis snapshots its injected services.
- **Provider replacement and HMR must preserve the same contract.** Fiber reactivation re-runs the waterfall, HMR carries the raw config to the replacement fiber, and a pending row accepts option changes without prematurely evaluating expressions against absent services.
- **A row cannot be inserted from inside a mounting plugin** — `tree.create` returns a prefixed id it then fails to resolve — so the Web runtime creates its conditional row (`dsh web --dev` and its reload chain) in the root tree after Loader settlement. A root-tree row is outside the include, so user-patch reapplication cannot touch it, and the incremental client-module scan adds it to the roster before any page loads — a browser arrives only after a human reads the URL line.
This leaves dependency ordering in Cordis activation and Loader interpolation, which own it. Rows keep their `inject` and config, Loader mounts the composition once, and the launcher only provides argv and process-lifecycle services.

三条框架事实塑造了这套机制:
- **profile 的各行位于根 include 的 `patches` 选项内部。** Include 声明了 `EntryGroup.key` 树载体标记(与 Group 相同),因此 Loader 让它的配置——条目与 patch 列表,包括 Include 自己的 `path`——保持字面值,而不是在 Include 上下文中递归求值嵌套的 `!!js` 节点;每个表达式都在其目标行的 fiber 中解析。
- **Cordis 只在所有声明的注入都已激活后才激活 fiber。** 每次激活前一刻,Cordis 会基于 fiber 自身上下文运行 `internal/config` waterfall;Cordis 快照注入服务之后,Loader 的监听器再插值原始配置。
- **提供方替换与 HMR 必须保持相同契约。** fiber 重新激活时会重跑 waterfall,HMR 会把原始配置带给替换 fiber,而待处理行可以接受选项变更,不会针对缺失服务提前求值表达式。
- **不能从正在挂载的插件内部插入一行**——`tree.create` 返回一个带前缀的 id,随后它自己解析不出来——因此 Web runtime 在 Loader 结算后在根树中创建其条件行(`dsh web --dev` 及其重载链路)。根树的行在 include 之外,用户 patch 的重新应用无法触及它;增量式客户端模块扫描会在任何页面加载之前把它加入名录——浏览器只会在人读到 URL 行之后到来。
这样,依赖顺序仍由负责它的 Cordis 激活与 Loader 插值流程处理。各行保留自己的 `inject` 和配置,Loader 只挂载一次组合,启动器只提供 argv 与进程生命周期服务。

Express all three with interfaces that already exist:
- **Conditional dev row.** `dsh-web-app` no longer ships a disabled `client-hmr` row; in development mode its runtime plugin creates the row in the root tree after Loader settlement with plain `loader.create`; a whole-tree name scan makes the creation reload-idempotent and defers to a user-configured `dsh-client-hmr` row (even a disabled one). A root-tree row is outside the include, so user-patch reapplication cannot restore it to disabled — the property the in-memory override existed for. The incremental client-module scan adds it to the roster before any page loads; a browser arrives only after a human reads the URL line, and its `EventSource` reconnects by spec. `Entry.enableRuntime`, its two state fields, and `enableRow` are deleted.
- **No conditional dev row.** The reload chain stops being conditional: `dsh-web-app` mounts the `client-hmr` row unconditionally and `--dev` is deleted, along with the web runtime's `mode` config, the mode-forked prompt contract, and the `DSH_WEB_MODE` bash variable. Without a rebuild watcher (`pnpm run dev:web`) rewriting client bundles, the chain polls unchanged files and stays idle, so the always-on row costs one stat-poll interval and an SSE route. `Entry.enableRuntime`, its two state fields, and `enableRow` are deleted with nothing replacing them.
- **Tree-carrier config.** Include declares the existing `EntryGroup.key` marker instead of implementing `EntryConfigResolver`; the Loader hook keeps every tree carrier's config literal. Include's own `path` loses `!!js` support — no configuration ever used it, and the pinning test now asserts the literal tree-carrier contract instead.
- **Launcher app-knowledge.** The launcher recognizes no app row. SIGTERM is a supervisor's ordinary stop request and exits 0 on every surface (SIGINT stays 130); the launcher cannot know whether the app considered its work complete, and the previous 143 depended on naming the headless row. Every boot watches its user patch layers — a one-shot surface exits through bounded shutdown, which disposes the watchers before the loop drains. The headless runner exits through `ctx.appExit` like any other app; its output streams are a package-internal `internals` test seam, and `ctx.headlessIo` is deleted.

- **Keeping `enableRuntime` but moving `enableRow` out of `dsh-cmdline`**: relocation fixes the package boundary but keeps the vendored state machine whose semantics (survives reapplication, rollback on failure) must be re-derived at every upstream sync.
- **`entry.update({ disabled: null })`**: mutates the entry's serialized options, so the next include reapplication restores `disabled: true` and unmounts the row mid-session.
- **SIGTERM 143 for one-shot surfaces via an app-registered signal handler**: the launcher's own handler races it for the exit code; winning that race needs a new launcher interface, which is the cost this change removes.
- **Keeping `--dev` with the row created at runtime**: an interim state of this change; it still needed a mode fork in the prompt contract, a `DSH_WEB_MODE` variable, and creation-versus-user-row arbitration, all to avoid an idle poll whose cost is negligible.
## Consequences
- A deployment that supervises `dsh --profile headless` with SIGTERM now observes exit 0 instead of 143; the caller sent the signal and sees no answer on stdout.
- The `--dev` reload row is not covered by the boot activation audit; a creation failure is logged, not fatal.
- The reload chain runs in every `dsh web` process; a deployment that must not expose `/plugins/events` disables the `client-hmr` row in its patch layer.
- One-shot runs mount the config-watch rows they previously skipped, costing a few milliseconds of startup.
- The vendored Loader/Include divergence shrinks by one protocol symbol and one state machine, and `rescope-vendor:check` passes again (the modification log's rescope entry is restored to the position its exact-edit anchor requires).

## 决策
三者全部改用已经存在的接口表达:
- **条件 dev 行。** `dsh-web-app` 不再随附禁用的 `client-hmr` 行;开发模式下其 runtime 插件在 Loader 结算后用普通的 `loader.create` 在根树中创建该行;全树名称扫描让创建具备重载幂等性,并让位于用户自行配置的 `dsh-client-hmr` 行(即便该行被禁用)。根树的行在 include 之外,用户 patch 的重新应用无法把它恢复为禁用 —— 这正是内存覆盖机制存在的理由。增量式客户端模块扫描会在任何页面加载之前把它加入名录;浏览器只会在人读到 URL 行之后到来,其 `EventSource` 按规范自动重连。`Entry.enableRuntime`、它的两个状态字段和 `enableRow` 一并删除。
- **不再有条件 dev 行。** 重载链不再是条件性的:`dsh-web-app` 无条件挂载 `client-hmr` 行,`--dev` 连同 web runtime 的 `mode` 配置、按模式分叉的提示词约定和 `DSH_WEB_MODE` bash 变量一并删除。没有重建 watcher(`pnpm run dev:web`)改写客户端 bundle 时,链路轮询到的文件从不变化、保持空闲,因此常开的行只花费一个 stat 轮询间隔和一条 SSE 路由。`Entry.enableRuntime`、它的两个状态字段和 `enableRow` 删除后无任何替代物。
- **树载体配置。** Include 改为声明已有的 `EntryGroup.key` 标记,不再实现 `EntryConfigResolver`;Loader 钩子让每个树载体的配置保持字面值。Include 自己的 `path` 失去 `!!js` 支持 —— 从未有配置用过它,固定该行为的测试改为断言字面值树载体约定。
- **启动器的应用知识。** 启动器不再识别任何应用行。SIGTERM 是监督进程的普通停止请求,在所有 surface 上以 0 退出(SIGINT 仍为 130);启动器无从知道应用是否认为工作已完成,而之前的 143 依赖于点名 headless 行。每次启动都监视用户 patch 层 —— 一次性 surface 经由有界关闭退出,关闭会先 dispose 监视器再排空事件循环。headless runner 像任何应用一样经 `ctx.appExit` 退出;其输出流是包内 `internals` 测试接缝,`ctx.headlessIo` 删除。

- **保留 `enableRuntime` 但把 `enableRow` 移出 `dsh-cmdline`**:搬迁修正了包边界,却保留了 vendored 状态机,其语义(在重新应用后仍生效、失败时回滚)在每次上游同步时都要重新推导。
- **`entry.update({ disabled: null })`**:改写条目的序列化选项,下一次 include 重新应用会恢复 `disabled: true` 并在会话中途卸载该行。
- **通过应用注册的信号处理器为一次性 surface 保留 SIGTERM 143**:启动器自己的处理器会与它竞争退出码;要赢得竞争需要新的启动器接口,而这正是本次变更要移除的成本。
- **保留 `--dev`、改为运行时创建该行**:本次变更的中间形态;它仍需要提示词约定里的模式分叉、`DSH_WEB_MODE` 变量,以及创建与用户自有行之间的仲裁,而这一切只为省下一个成本可忽略的空闲轮询。
## 后果
- 用 SIGTERM 监督 `dsh --profile headless` 的部署现在观察到退出码 0 而非 143;信号是调用方自己发的,且 stdout 上没有答案。
- `--dev` 重载行不在启动激活审计的覆盖内;创建失败只记录日志,不致命。
- 重载链在每个 `dsh web` 进程中运行;不得暴露 `/plugins/events` 的部署应在其 patch 层禁用 `client-hmr` 行。
- 一次性运行会挂载之前跳过的配置监视行,启动多花几毫秒。
- vendored Loader/Include 偏差减少一个协议符号和一台状态机,`rescope-vendor:check` 重新通过(修改日志的 rescope 条目回到其精确编辑锚点要求的位置)。
