fix(#3839): hook tables say PreToolUse (validate-commit) and SessionStart (session-state) (#4041)

* test(#3839): docs hook tables must match surface registrations (failing first) * docs(#3839): hook tables say PreToolUse for validate-commit, SessionStart for session-state gsd-validate-commit.sh is registered PreToolUse (src/runtime-hooks-surface.cts; its exit-2 block IS the contract — a post-tool hook cannot prevent a commit) and gsd-session-state.sh is registered SessionStart (session orientation, not post-tool tracking). Both rows said PostToolUse in ARCHITECTURE.md and the three INVENTORY locales; the issue asked for a neighbouring-row scan, which is how the session-state row was found. All other rows in the four tables verify against the surface. * fix(#3839): review fold-ins — 10 more wrong rows in ko-KR/pt-BR/zh-CN, parser authority + drift pins Adversarial review found the same two wrong rows shipped in five more files the issue's table missed (ko-KR ARCHITECTURE+INVENTORY, pt-BR ARCHITECTURE+INVENTORY, zh-CN ARCHITECTURE) — all fixed; DOC_TABLES now covers all ten shipped tables. The parity parser unioned only the Kimi mirror list, silently exempting agent-isolation-guard (registered via the dynamic preToolEvent push): probes are now parsed too, with bare hook names resolved against hooks/ ground truth and dynamic event variables resolved to their canonical (non-Gemini) events; an exact-set pin replaces the loose size guard. allow-test-rule marker carries the issue ref; unverified-ceiling 280→281 (audited: the new marker is legitimate — the suite reads product docs whose text is the contract). * fix(#3839): register the hook-table parity suite in the docs-guard lane The new suite reads ten docs/ paths, so lint-docs-guard-registration requires it in the docs-guard registry — the first GREEN bench run caught the omission (the RED run's docs-guard failures were the same signal, previously misread as marker fallout). * chore(#3839): changeset fragment (pr number backfilled after PR creation) * chore(#3839): backfill changeset PR number (4041) --------- Co-authored-by: sim <sim@local>
