Merge remote-tracking branch 'origin/master' into codex/basic-session-search

Conflict resolutions:

- `session.list`: master's projection columns fold into the PR's cancellable,
  batched `listVisibleSessionSummaries`, which `session.search` shares as its
  visibility baseline; master's goal helpers stay beside it.
- Client sessions face: master narrowed `ctx.sessions` to `ISessions`, so the
  search verb and its protocol-constant bound are declared there and the
  test-runtime double implements them (recorded, empty page unless a scenario
  stubs hits).
- `WorkspaceBrowser`: master's per-row Rename wiring rides the PR's search
  results view; the tree keeps the PR's query-free derivations.
- `dsh web` bin: the PR's shutdown-handlers-before-readiness order with
  master's boot-time LAN address snapshot.
- `session-query-sqlite`: master's `SCHEMA_VERSION` 7 stands; the PR's bump
  carried no schema change.
- Specs: master wraps assistant/steering message payloads and requires an
  `application/json` carrier request, so the search fixtures and tests follow.
- Web aria goldens keep master's recording plus the PR's search placeholder;
  the navigation-panes inventory keeps master's terminal-card golden next to
  the PR's search-results golden.
