GitHub Repository Monitor

Create a cron automation that polls a single GitHub repository on a configurable schedule (default: every minute).

When a comment on an issue or PR contains the trigger phrase (default: @OpenHands) it:

1. Posts a GitHub comment acknowledging the request with a conversation link.
2. Creates an OpenHands conversation pre-loaded with the issue/PR title, body, labels, and recent comment history for full context.
3. Posts a summary GitHub comment when the conversation finishes.

On every subsequent run:

• New trigger comments on an already-tracked issue/PR are forwarded to the running conversation (or re-open a previously closed one).
• When a conversation goes idle/finished/error the agent's final response is posted back as a GitHub comment.
