"""Add indexed_ok / indexed_at to playbooks — durable index-state tracking.

``approve`` flips a draft to APPROVED and the post-commit ``index_approved``
step embeds it into the PLAYBOOKS RAG index. The index write is best-effort
(embedder down → swallowed + logged), so an Ollama restart mid-approval-burst
left a row APPROVED but absent from the corpus — the Auditor saw "approved"
while agents never surfaced the procedure. These two columns record whether
the index write actually landed: ``indexed_ok`` is False on the status flip
and set True only inside a successful ``index_playbook`` result;
``indexed_at`` timestamps it. A startup reconcile re-indexes
APPROVED-but-``indexed_ok=False`` rows. Additive and default-off (existing
approved rows are treated as unindexed and reconciled on the next startup).
