feat(config): add pwsh cfgen + ps1 file watcher

This commit adds a command to generate application-specific
configuration in the format of a PowerShell ps1 file, as well as the
ability to automatically launch a komorebi.ps1 configuration file on
startup.

If a komorebi.ps1 file is found and launched at startup, the
watch-configuration command will watch and hot reload this file when any
changes are made.

A sample komorebi.ps1 file has been added to the root of the repository,
along with a sample whkdrc file, showing how the two can be used
together to replace AHK.
