Pull request overview

This PR adds a new v4 runner command endpoint to update an experiment’s description, wiring it through the router into runner implementations and adding endpoint-level tests. It extends the runner interface with an update_description capability and implements it for both local and SSH runners.

Changes:

• Add /v4/runners/command/update-experiment-description endpoint guarded by runner endpoint configuration.
• Implement update_description() in LocalRunner and SSHRunner, and add the method to the base Runner interface.
• Add tests covering disabled endpoint, valid request, invalid profile, and runner failure.
