Fix /light and /dark commands: Add LD_LIBRARY_PATH to quickshell wrapper

- Add LD_LIBRARY_PATH to quickshell wrapper for execDetached child processes
- Ensures /light and /dark commands have proper Python environment
- Child processes spawned by Quickshell.execDetached() now inherit system libraries
- Fixes 'No module named PIL' error when using search commands
