Add migration to update existing Chromium/Brave configs with crash fix

Adds migration script to append --disable-features=WaylandWpColorManagerV1
to existing users' chromium-flags.conf and brave-flags.conf files.

The script:
- Checks if config files exist before attempting to modify them
- Uses grep to verify the flag isn't already present
- Only adds the flag and explanatory comment if needed
- Handles both Chromium and Brave configurations

This ensures existing Omarchy users get the Hyprland crash workaround
without needing to manually update their configs.
