## PR Checklist
This PR improves FancyZones CLI usability with three enhancements:

1. **PowerShell GUID compatibility**: Users can now pass GUIDs without
braces (e.g., `0CEBCBA9-9C32-4395-B93E-DC77485AD6D0`), avoiding
PowerShell's script block interpretation issue
2. **Subcommand help**: Added `--help` support for individual commands
(e.g., `FancyZonesCLI set-layout --help`)
3. **Friendly error messages**: When PowerShell incorrectly interprets
`{GUID}` as a script block, displays a helpful message instead of
cryptic errors
