Address Copilot review on #925:
- Full closet rebuild whenever the content hash differs from prior
state, not only on entry-count growth. Without this, an in-place
edit (same entry count, different body) updated the drawer but
left the closet/search index stale — defeats the verbatim guarantee
at the search layer even if the drawer is correct.
- Legacy size-only skip path now records the computed content_hash
back into state so subsequent runs use the strict hash check
instead of remaining on the size-only path indefinitely.
- Test updates: typo direction in the regression test now matches the
comment (typo "Teh" → fix "The"), assertion now also checks the
closet collection reflects the edit, and a new test exercises the
legacy-state backfill path.
