Fix compilation errors

- Remove nonexistent confDebounce field from WatchConfig (fsnotify 0.4.4.0)
- Remove unused Generic deriving and GHC.Generics import
- Replace .!= with fromMaybe (not re-exported by Data.Yaml)
- Add missing Data.Text import in Main.hs
- Use git -C flag in runGitIn to run in the correct repo directory
- Clean up unused imports
