Fix automatic workflow run updates with improved polling mechanism

[spboyer]

Description

This PR fixes issue #229 where newly triggered workflow runs required manual refresh to see updates in the UI. The extension now automatically polls for workflow run updates and reflects changes in real-time.

Changes

Enhanced Polling Mechanism

• Added checks for window focus and view visibility before polling to prevent unnecessary API calls
• Enhanced logging to show run status and conclusion during polling attempts
• Improved cleanup of polling intervals when runs complete or polling attempts are exhausted

Key Improvements

1. Respects window focus and view visibility, optimizing API usage
2. Workflow runs now update automatically without requiring manual refresh
3. Proper cleanup prevents memory leaks and unnecessary API calls

Fixes #229

Testing

The fix ensures that:

• When a new workflow is triggered, it automatically appears and updates in the extension view
• Re-running workflows shows progress updates in real-time
• Polling stops when runs complete
• API calls are minimized when the window is not focused or the view is not visible

Pull request overview

This PR implements an automatic polling mechanism to update workflow runs in real-time without requiring manual refresh, addressing issue #229. The solution adds intelligent polling that respects window focus and view visibility to minimize unnecessary API calls.

Key changes include:

• Automatic polling for active workflow runs (in_progress, queued, waiting, requested) with a 4-second interval for up to 15 minutes
• Window focus and view visibility tracking to pause polling when the extension is not in use
• Enhanced workflow trigger command that waits for new runs to appear and automatically starts polling them
