fix(nlpm): resolve 5 critical defects from NLPM audit

- Add missing name: field to workstreams and reapply-patches commands
- Add AskUserQuestion to review-backlog allowed-tools
- Fix conflicting path references in gsd-user-profiler (use ~/.claude/get-shit-done/... convention)
- Add allowed-tools to cleanup, help, and join-discord commands
- Remove empty stub Step 5 from reapply-patches (dead bash comment block)

Closes #1578
