fix(cli): hide stub commands from help (batch group, workflow build/run/deploy)

Don't advertise features that aren't implemented yet:
- batch group: hidden entirely (all 4 commands are stubs)
- workflow build/run/deploy: hidden individually (other workflow
  commands like list/get/create/update/fork are implemented)

Hidden commands still work and give clear 'not yet implemented' messages.

374 tests pass, all linting clean.
