<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>
