cut-a-release

Cut an npm release of kcp-agent (the TypeScript/CLI package) — bump the version in every place the release tests check, re-sign knowledge.yaml, dispatch release.yml, and confirm the npm publish that release.yml hands off to ci.yml. Use when asked to release, publish, or tag a new kcp-agent version. Does NOT cover the separate java-release.yml / rust-release.yml version tracks, which version independently.
