Sandbox Violation Notifications

What: Real-time status bar notifications when the sandbox blocks operations.

How it works:

• Displays "⧈ Sandbox blocked N operation(s) (ctrl+s to see logs)" in the status bar
• Shows count of newly blocked operations
• Auto-hides after 5 seconds
• Press Ctrl+S to view detailed violation logs

Details:

• Only appears when sandboxing is enabled
• Provides immediate feedback without interrupting workflow
• Helps diagnose permission issues during development
• Uses existing sandbox violation store infrastructure (added in v1.0.122)
