plugins/lint/hooks/hooks.json was no longer produced from .apm/hooks/,
so check-plugin-content-sync failed on it at HEAD:
DRIFT plugins/lint/hooks/hooks.json: stale, no longer produced from .apm/hooks/
Surfaced by running sync-plugin-content.sh --all during unrelated work.
Unrelated to ADR-0020; committed separately so the contract change stays
reviewable on its own.
Per ADR-0017's 2026-08-14 amendment, a hooks.json a sync no longer
generates is deleted as stale.
