fix(claude): correct gh pr create snippet and allow AskUserQuestion in /ship skill

- Fix line-continuation bug in the Phase 6 gh pr create example: move the
  FEAT/FIX note above the block so every flag carries a backslash.
- Resolve --base dynamically via `gh repo view` so the skill works on
  repos whose default branch is not `main`.
- Add `AskUserQuestion` to allowed-tools so the secrets-scan hard-stop
  can present its structured three-option prompt.
