chore: remove all deprecated code

- Remove createThreadCas alias (CAS is global, not per-thread)
- Remove formatSkillDoc() legacy compat shim
- Remove help command (replaced by skill)
- Remove all 13 DEPRECATED_ALIASES flat commands + printDeprecation
- Fix CAS prompts in develop roles: remove stale <THREAD_ID> param
- Update README.md to remove createThreadCas reference
- Net: -86 lines, 241 tests pass

Closes #114
