The October 8 API parity run fails on 12 missing methods; #40 only records the earlier three. Add all nine agents.conversations.* routes, agents.sessions.rename / setStatus, and blocks.validate, restoring parity without changing its checks or exclusions.

The agent methods use JSON POST, including getCanvas and listViews, as specified by Slack's reference. blocks.validate uses form POST: live token-free probes showed JSON requests were ignored, while the same JSON-encoded blocks string sent as a form returned ok: true. Add routing coverage and a form-payload/response regression test, register both families, update the 180-method documentation/catalog, and regenerate the committed bundle and declarations. Verification details and source links are in docs/verification.md.

Validation:

• pnpm run build: lint, typecheck, 258 tests, bundle and declaration generation passed.
• Unchanged node scripts/check-parity.mjs: passed against 280 official SDK methods.
• All 12 new routes verified live through dist/bundle.js: 11 agent routes returned not_authed; token-free blocks.validate returned ok: true.
• Existing seven-check node scripts/verify-live.mjs no-token suite passed; git diff --check passed.

Authenticated agent operations were not exercised. No conversation creation, merge or deployment was performed.

Fixes #40.
