<objective>
Safe git revert — roll back GSD phase or plan commits using the phase manifest, with dependency checks and a confirmation gate before execution.

Three modes:
- **--last N**: Show recent GSD commits for interactive selection
- **--phase NN**: Revert all commits for a phase (manifest + git log fallback)
- **--plan NN-MM**: Revert all commits for a specific plan
</objective>
