Notifications for job starts and completions

[nicktallen]

Problem

Users have no proactive notification when a runner picks up a job or when a job completes/fails. They must manually check the menubar.

Proposed Solution

Use macOS UserNotifications to alert when:

• A runner picks up a new job (shows repo + workflow name)
• A job completes successfully
• A job fails

Acceptance Criteria

• macOS native notifications via UserNotifications framework
• Notification on job start (show repo, workflow, runner name)
• Notification on job completion (success/failure)
• Clicking notification opens the GitHub Actions run URL (ties into Add GitHub Actions job link to menubar status when runner is executing #26)
• Configurable: enable/disable per event type in Settings
• Respect macOS Focus/Do Not Disturb

Notes

Listed in README under "Planned Features." Filing to track formally. Complements #26 (job link in menubar).
