Function setup_panic_hook

pub(crate) fn setup_panic_hook()

Sets up a comprehensive panic hook that ensures proper terminal restoration.

This function configures a custom panic handler that:

• Immediately disables raw terminal mode
• Exits alternate screen mode
• Clears the terminal display
• Provides user-friendly error messages with context-specific help
• Exits the application cleanly

The panic hook is designed to handle common failure scenarios like:

• Missing environment variables (PROJECT_ID, AWS credentials)
• API authentication failures
• Network connectivity issues

Safety

This function should be called early in main() before any terminal operations to ensure proper cleanup in all failure scenarios.
