feat(rawcli): ipython-style completion (Phase 6)

- completer.py: RawCompleter completes the leading command token —
  control verbs + the identified transponder's catalog commands — with
  each command's help as the completion meta (tooltip). `help <cmd>`
  completes catalog command names.
- app: wire the completer with complete_while_typing (live menu) +
  AutoSuggestFromHistory (inline hints) for the ipython feel.

Completes the 6-phase rawcli plan. 4 new tests (verb/catalog completion,
tooltips, help-arg completion).
