chore(cli): typecheck clean (10 → 0)

- broker-actions: msg-status section header used out-of-scope `id`
  variable; was a real bug (renders "message undefined…" on the JSON
  path). Fixed to use the in-scope lookupId.
- exit-codes: add IO_ERROR (10) — referenced in three places by
  platform-actions but never declared.
- types/text-import.d.ts: declare wildcard `*.md` module so Bun's
  text-import attribute used by skill.ts typechecks.
- ipc/server: cast PeerSummary/SkillSummary through unknown before
  spreading into Record<string, unknown>.
- mcp/server: typed JSON.parse for SSE events.
- bridge/daemon-route: import path with .ts → .js (esm).
