feat: align SDK with updated OpenAPI spec and add missing unit tests

- Update generated types from new openapi.yaml (capsule stats, usage,
  metrics, pause/resume lifecycle, host/channel management, auth flow)
- Add Capsule pause/resume/ping/getMetrics lifecycle methods
- Add Capsule.waitForReady abort signal support
- Add PtyManager.connect and PtySession disposal
- Fix HttpClient empty-body response handling (content-length: 0)
- Add streamProcess() to CommandManager for background process streams
- Add integration tests for capsule lifecycle, git, and PTY features
- Add unit tests for AsyncQueue error paths, PtySession.close,
  Git.checkout without create, Git.add single string,
  Notebook.execCell error case, and PtyStartOptions fields
