v0.3.0

This maintenance release hardens the documented deployment and updates all dependencies. Two changes are important for existing users:

• Deployment defaults changed: the Compose files now bind the proxy to 127.0.0.1, and workers run as a non-root user with a seccomp profile (#93). Review your deployment if you exposed the proxy differently.

• Playwright is now 1.62.1: remote clients must use a matching Playwright version to connect.
