docs: qualify plan-mode timing and workspace no-write claims

ds-review-bot round 3:
- set() after a turn's final step lands in a later turn (selection
  never forces continuation) — the same-turn phrasing overstated the
  guarantee; set() JSDoc + subsystem page (both languages).
- Workspace attach/insert/detach no-op claims now carry the
  filtered-candidate-prune caveat: mutate() durably prunes stale
  candidates even when the requested change is a no-op, a state the
  sessionIds contract explicitly permits; Workspace fence re-synced on
  both page sides; catalogs regenerated.

[dsh-host-webserver](../../packages/host/webserver) is the web-shape HTTP carrier for the GUI host: a single `node:http` plugin providing `ctx.httpServer`, a named-route registry plus index.html transform taps over a static dist fallback. It is not part of the agent-loop spine and not a capability seam — it knows no harness concepts, and every feature surface (the `/api` bridge, plugin bundles, the HMR event stream) is a route some other plugin registers ([layering note](../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.md)). Web (browser) shape only: Electron loads dist over `file://` and carries fetch over an IPC bridge, not this server.

Match order is fixed: exact table first, then longest matching prefix, then the static dist fallback. Registration order carries no request-facing semantics — named routes are composed to be disjoint, and the fallback answers anything not yet claimed during the boot window. The fallback keeps locked semantics: non-GET/HEAD is 405, traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), and unknown extensions ship as octet-stream ([`static.ts`](../../packages/host/webserver/src/static.ts)).
Match order is fixed: exact table first, then longest matching prefix, then the registered fallback. Registration order carries no request-facing semantics — named routes are composed to be disjoint, and the fallback seat answers anything no named route claims; one owner only, a second registration throws. The shipped Web composition claims the seat with [`dsh-frontend-static`](../../packages/host/frontend-static/src/index.ts), the SPA dist server with locked semantics: non-GET/HEAD is 405, traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), and unknown extensions ship as octet-stream.
## Config
```ts type-equiv
/** Gateway config: listen address plus the static dist anchor (injected by the composing app, never self-resolved). */
/** Gateway config: the listen address. */
interface Config {
/** Listen host; the two supported values are loopback and all-interfaces. */
host: '127.0.0.1' | '0.0.0.0'
/** Listen port; zero requests an OS-assigned port. */
port: number
/** Absolute path of index.html inside the static root (dist location is workspace knowledge of the app). */
distIndex: string
}
```
`host` accepts only `127.0.0.1` (default posture) and `0.0.0.0` (deliberate network exposure); there is no TLS, auth, or origin policy, so a non-loopback bind exposes the server to that network. `distIndex` is an assembly fact the composing app resolves and injects.
