What Happened
- A wrong function name in the skills manager import caused an ImportError that blocked all skill lifecycle operations; correcting `get_default_skill_directories` to `get_default_skill_dirs` restores `create_skill`, `edit_skill`, `delete_skill`, `patch_skill`, and `write_skill_file` so the feature works again.
