Memex 0.7.2

Memex 0.7.2 fixes the seven findings of the post-release review of 0.7.1, each verified and reproduced before it was fixed.

Extraction-rules overlay

• The never_extract check runs on the classifier note exactly as it is persisted — the joined notes as well as each note — so a pattern that only matches across a note boundary can no longer reach the Chronicle. (#30)

Overlay locks and quarantine

• Abandoned-lock recovery is serialized through a <lock>.reclaim mutex: only its holder re-checks and unlinks, so a writer that acquired the lock in between is never stolen from. (#29)
• The quarantine file's read-merge-rename runs under its own lock with the stamp compare-and-swap as a backstop, and in-memory quarantine rows mirror the file once written, so a memex gate quarantine clear from another process is honoured and never undone. (#29)
• memex gate quarantine clear honours --dry-run; it takes no --expect-revision, and the docs now say so. (#29)

Documentation

• GUIDE.md and WEBUI-WORKSPACE.md now state that memex status, the overview attention card and the jobs table show every hold family, and that the embedding-model switch is a later 0.7.x release (#118), not 0.7.1.
