feat: delegate deterministic workflow operations to gsd-tools CLI

Add 10 new CLI commands that replace manual AI orchestration of
mechanical, deterministic operations — saving tokens and reducing
errors on the most complex GSD workflows.

New commands:
- phase add <desc> — append phase to roadmap + create directory
- phase insert <after> <desc> — insert decimal phase
- phase remove <N> [--force] — remove phase with full renumbering
- phase complete <N> — mark done, update state + roadmap, detect milestone end
- roadmap analyze — unified roadmap parser with disk status
- milestone complete <ver> [--name] — archive roadmap/requirements/audit
- validate consistency — check phase numbering and disk/roadmap sync
- progress [json|table|bar] — render progress in various formats
- todo complete <file> — move todo from pending to completed
- scaffold [context|uat|verification|phase-dir] — template generation

Updated workflows to use new CLI commands:
- remove-phase.md: 13 manual steps → 1 CLI call + confirm + commit
- add-phase.md: 6 manual steps → 1 CLI call + state update
- insert-phase.md: 7 manual steps → 1 CLI call + state update
- transition.md: roadmap/state updates delegated to phase complete
- progress.md: roadmap parsing delegated to roadmap analyze
- complete-milestone.md: archival delegated to milestone complete

75 tests passing (33 new).
