chore: three small cleanups from the v2.2.0 merge review

Browse source 
1. clients/web/.npmignore's explanatory comment still said the root "files"
   allowlist restricts publishing to build/ and dist/ and that everything else
   under clients/web "stays out regardless". #1934 added clients/web/static to
   that allowlist, so the claim was false — in a file that exists precisely
   because a packaging contract was misread once. Name static/ and say why it
   ships (read from disk at runtime by sandbox-controller.ts, at a path
   relative to the runner dir).

2. Replace the four unjustified `as unknown as Response` doubles in
   useServers.test.tsx with real Responses over real ReadableStreams: a
   null-body Response for the `!res.body` guard, a stream whose pull throws for
   the reader-rejects case, and pull-driven streams for the multi-frame and
   priming-comment cases (pull runs once per read, so the counting and the
   blocking second read behave exactly as the hand-rolled reader doubles did).
   The doubles are now structurally type-checked against the Response API.

3. scripts/smoke-web-app.mjs orphaned the MCP test server on a readiness
   timeout: startMcpServer() returned the child only once the announcement
   line matched, so a child that was alive but never announced left `mcpServer`
   unassigned, shutdown() could not stop it, and process.exit(1) left it
   holding its port. Publish the child to `mcpServer` the moment it is spawned,
   so every throw path is covered by teardown.

Closes #2000

* The child is published to `mcpServer` the moment it is spawned rather than
* handed back on success, so `shutdown()` can stop it on every throw path.
* Returning it only after the announcement matched left the readiness timeout
