"""F011 — PlaybookService.reject must de-index the playbook.

A rejected/archived playbook that was previously approved stays in the
PLAYBOOKS RAG index (no de-index on reject/archive), so it keeps surfacing
in agent briefings as a stale, no-longer-canonical procedure. The fix
mirrors the index-on-approve path: ``reject`` calls an
``_unindex_playbook`` helper (gated on ``org_memory_enabled``, best-effort)
that removes the playbook's chunks + tracking row.
