fix(hooks): make the output more uniform and delineated (#2343)

* fix(hooks): Consistent logging + skip when empty too

- Use "Searching for scripts [...] located in [...]" consistently (i.e. for each hook_folder_path instead of only for some / under some conditions)
- Skip early if a given hook folder is empty too (not just nonexistent)
- Add feature name (hooks) to all messaging for clarity
