chore: remove deprecated workflows:* skill aliases (#284)

* docs: capture codex skill prompt model

* fix: align codex workflow conversion

* chore: remove deprecated workflows:* skill aliases

The workflows:brainstorm, workflows:plan, workflows:work, workflows:review,
and workflows:compound aliases have been deprecated long enough. Remove them
and update skill counts (46 → 41) across plugin.json, marketplace.json,
README, and CLAUDE.md.
