Merge origin/master into feat/website-docs

Conflict resolution notes:
- package.json/run-gates: both sides' new doc-sync gates kept (master's
  scoped-events/readme gates + this branch's website-api/website-yaml);
  js-yaml devDeps deduped (master added them independently).
- pnpm-workspace/knip: website AND python/sdk-runtime entries kept.
- doc-typecheck/verify-type-equiv: master's condensed headers kept, website
  glob retained in both scan scopes.
- vendor/cordis/src/fiber.ts: master's lifecycle-hardening code taken; this
  branch's richer FiberState JSDoc reapplied on top. vendor/README.md logs
  both local modifications (hardening = 6, JSDoc enrichment = 7).
- pnpm-lock: regenerated from master's side (pnpm install).

Post-merge sync the gates forced (the system working as designed):
- verify-website-yaml caught 4 stale plugin names from master's package
  reorg (dsh-stdio-agent -> dsh-stdio-demo, dsh-acp-agent -> dsh-acp-demo);
  8 references fixed across guide/ and develop/.
- gen-website-api picked up master's 6 new services automatically
  (ctx.approval/permission/sandbox/sessionQuery/skills/tasks -> 6 new pages
  + sidebar); api/index.md hub updated to list them.
- AGENTS.md budget ceiling 1370 -> 1400: the website rows (layout line + two
  command lines) and master's own growth collided with the old ceiling; all
  three website rows are load-bearing (new top-level dir, new CI command).
