The checkbox read "Clear saved API key (disable pool first)", but the
panel never defines "pool" and saving with it ticked on an enabled worker
was rejected by the backend.
- Disable the checkbox while the worker is enabled, with a tooltip saying
to turn the worker off first. Also disable it when no key is saved.
- Use "worker" instead of "pool" in user-facing serverless errors, the
serverless guide and the README entry.
* fix: isolate local worker databases and avoid port conflicts
* fix: harden local worker startup preflight and database paths
Handle auto-launch before the master binds, allow TIME_WAIT restarts without accepting active listeners, resolve relative paths in the worker cwd, and round-trip SQLite URLs through SQLAlchemy. Add regressions and remove the README additions.
