docs: generate each subsystem's cordis surface into its own page; delete the flat catalogs

Rebuild of the region machinery (PR3) on the post-#904 Typert projection:
renderPageRegion/renderInheritedPage live in dsh-typert-generator beside the
projection; scripts/gen-cordis-catalog.ts owns the curated SERVICE_PAGE /
EVENT_SCOPE_PAGE / SERVICE_WALK_EXEMPTIONS / LINK_MAP partition (fail-loud in
both directions, with the independent Context-merge scan backstopping the
projection's blind spot), spliceRegion, and the guarded pair auto-record.
docs/cordis-catalog/ is deleted: the flat events/services catalogs dissolve
into per-page regions and docs/cordis-catalog/core moves to docs/cordis-api/
with the inherited tier as its own generated page. The partition absorbs the
post-regrouping surface: ctx.typert → invariants.md, ctx.directoryPicker →
workspace.md, skills/* events → skills.md, and the four launcher-provided tui
accessor values join the named exemptions.

 开发环境下，[dsh-client-hmr](../../packages/client/hmr/README.md) 是注册表的监视驱动：它的 Node 半从同步取得的基线出发，对图中每一行的 bundle 做 stat 轮询，变化时调用 `rebuilt(id)`，经 `onGraphChanged` 重新同步监视集合，并通过 SSE（Server-Sent Events）把 rev 变化广播给浏览器半。生产环境的图完全不含 HMR（热模块替换）行；模块宿主自身从不监视文件。

+## Cordis surface
+
+Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — this section is byte-identical in both language sides of the page. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.md#dispatch-modes), and the framework-inherited `ctx` surface lives in [cordis-api/inherited.md](../cordis-api/inherited.md).

+The web plugin table service: incremental dshClient scan + wire composition + bundle route + index tap. Construction runs the activation scan synchronously — a malformed declaration or missing bundle among the already-loaded entries aggregates into one loud throw (FAILED fiber; the boot activation audit reports it).
