* chore(core): convert help.md to native skill directory
Migrate the single-file help.md task to a bmad-help/ skill directory
following the pattern established by bmad-review-adversarial-general.
Update module-help.csv to use skill: reference and remove the entry
from the parent manifest. Fix 7 BMM workflow step files that had
hardcoded file path references to the now-relocated help task.
