Upgrade from 0.1.x to 0.2.0

AgentsKit Chat packages are a fixed version group. Upgrade every installed @agentskit/chat* package to 0.2.0 in the same change and commit the updated lockfile.

{
  "dependencies": {
    "@agentskit/chat": "0.2.0",
    "@agentskit/chat-protocol": "0.2.0",
    "@agentskit/chat-react": "0.2.0",
    "@agentskit/chat-server": "0.2.0"
  }
}

Existing definitions and renderer shells require no source migration. The new backend APIs are additive. Applications adopting them should configure the documented server boundary, keep corpus and persona authority in trusted server configuration, and limit client hosts to documented identity, endpoint, and presentation seams.

After updating, run the host typecheck, tests, production build, and a real streaming smoke test. A service that emits Ask NDJSON may use the canonical NDJSON content type; 0.2.0 also recognizes valid records when an intermediary incorrectly labels the response as text/plain.

See the backend guide, Ask protocol, and deployment guide.
