Add 12 commands that exist in GSDv1 but had no v2 equivalent:
High priority:
- ship: Create PR from milestone artifacts (title, body, metrics)
- add-slice: Append slice to roadmap via engine updateRoadmap()
- insert-slice: Insert slice at position with reordering
- remove-slice: Remove pending slice (--force for planned slices)
- do: Natural language routing via keyword matching (30 routes)
- session-report: Session cost/tokens/work summary (--json, --save)
Medium priority:
- backlog: Structured backlog with 999.x numbering (add/promote/remove)
- pr-branch: Clean PR branch filtering .gsd/ commits via cherry-pick
- add-tests: LLM-dispatched test generation for completed slices
- map-codebase: Codebase analysis (tech/arch/quality/concerns)
All slice mutations go through the engine's updateRoadmap() command,
preserving the single-writer architecture. No direct markdown edits.
Includes 46 unit tests across 6 test files, 2 prompt templates,
catalog entries with nested completions for all commands.
