Add generated persistence log event catalog with freshness + completeness gates

docs/persistence-catalog/log-events.md enumerates every SessionEventMap
member — the owning dsh-session vocabulary plus the dsh-compact and
dsh-hook-protocol declaration merges — with payload, surface/log-only badge,
JSDoc prose, and declaration site. scripts/gen-persistence-catalog.ts is a
pure AST pass in the gen-cordis-catalog mold: verify-persistence-catalog
(--check) joins doc-sync, so a stale committed catalog fails pre-push and CI.

The walk enforces JSDoc completeness (every member needs description prose;
@mode is rejected as a category error — log events do not dispatch on the
cordis bus), derives the surface badge from the SurfaceEventType union with a
stale-member cross-check, and hard-errors on duplicate declarations. Payloads
render through the TypeScript printer so newline-separated multi-line type
literals still emit valid one-line fragments.

Documented the five previously JSDoc-less core events (turn/step boundaries,
tool/call), removed the two stray @mode tags on the hook/* merges, and
replaced the hand-restated event enumerations (session.md hook/* table,
compact README table, hook-protocol README bullets, session README name-list
— whose merge note had already drifted) with links to the catalog. RFC:
docs/rfc/implemented/process/2026-07-04-persistence-log-catalog.md.
