[ganya002]

What changed

• Replace the wide Clamshell ON/OFF text with a compact square menu bar icon
• Laptop icon when Clamshell Mode is ON, moon icon for normal sleep, question mark for unreadable state
• Cleaner native menu with current mode, battery percentage, and power source
• Warning when sleep is disabled while running on battery
• Automatic status refresh every 60 seconds and whenever the menu opens
• Better handling of pmset failures instead of silently assuming OFF
• Installer now preserves the current sleep state instead of enabling Clamshell Mode as a permission test
• Tighten sudoers from wildcard disablesleep * to only disablesleep 0 and disablesleep 1
• Validate the sudoers rule with visudo
• Uninstaller restores normal sleep before removing permissions
• Version bump to 2.0.0
• Add macOS GitHub Actions validation for Swift, plist, and shell syntax
• Rewrite README for the new behavior

This keeps the utility tiny and native while making it much less intrusive in a crowded macOS menu bar.
