Group skills by scope in the Skills page

What feature would you like to see?

In the Codex macOS app, the Skills page currently displays all skills in a flat grid. It would be much more useful to group skills by their scope (have headers for each scope):

1. System — built-in skills provided by Codex (e.g., Skill Creator)
2. User — global skills installed at the user level (e.g., ~/.claude/skills/)
3. Project — project-level skills scoped to the current working directory

This grouping would make it easier to understand where each skill comes from, manage overrides, and quickly find the right skill.
