feat: Rename workflows:* to ce:* with backwards-compatible deprecation (v2.38.0)

Add ce:plan, ce:work, ce:review, ce:brainstorm, ce:compound as the new
primary commands. Old workflows:* names remain as thin deprecation wrappers
that warn and forward with disable-model-invocation.

Also removes the unused GitHub Pages documentation site.
