fix(repair): address Copilot review on #1227

Five Copilot review issues + the Python 3.9 CI failure rolled into one
follow-up:

* Replace ``dict | None`` annotated assignment with a type-comment so
  module load doesn't evaluate PEP 604 syntax on Python 3.9 (CI red).
* Drop ``mempalace repair rebuild`` — the CLI only ships ``mempalace
  repair`` (rebuild) and ``mempalace repair-status``. Updated all
  user-facing messages, docstrings, and test assertions.
* Replace ``_get_client()`` in ``tool_search`` with the safe
  ``_refresh_vector_disabled_flag`` probe so the fallback isn't
  defeated by the very chromadb client load it's trying to avoid.
* Short-circuit ``tool_status`` to a pure-sqlite reader
  (``_tool_status_via_sqlite``) when divergence is detected so wing /
  room counts come back without ever opening the persistent client.
* Wrap the recency-window query in ``_bm25_only_via_sqlite`` with an
  ``id``-ordered fallback so legacy schemas missing ``created_at``
  don't break BM25 search.

New test covers the sqlite-status short-circuit. 1409 tests pass.
