feat(config): add cfgen for apps based on yaml def

This commit introduces a configuration generator for
application-specific config options passed to the cli via a file path.

The hope is to have a public repository that any user can contribute
application-specific configs and fixes to, and for the generated AHK to
be available to any new user as part of the initial setup to make the
onboarding as frictionless as possible.
