feat: enhance notification URLs with issue links and tool aliases

Improvements to notification system for better traceability:

1. DEV Completion Notifications:
   - Always include issue URL (📋 Issue: ...)
   - Include PR/MR URL when available (🔗 PR: ...)
   - Issue URL serves as fallback when PR/MR not found
   - Both URLs shown when PR/MR exists for maximum traceability

2. QA Pass Notifications:
   - Now include issue URL (📋 Issue: ...)
   - Provides direct link to resolved issue

3. Tool Aliases:
   - Added 'work_finish' as alias for 'task_complete'
   - Added 'work_start' as alias for 'task_pickup'
   - Added 'status' as alias for 'queue_status'
   - Matches naming used in AGENTS.md documentation

Example DEV notification:
✅ DEV done #106 — Enhanced notification URLs
📋 Issue: https://github.com/user/repo/issues/106
🔗 PR: https://github.com/user/repo/pull/107
Moved to QA queue.

Example QA notification:
🎉 QA PASS #106 — All tests passed
📋 Issue: https://github.com/user/repo/issues/106
Issue closed.
