Create all phases necessary to close gaps identified by `/gad:audit-milestone`.
Reads MILESTONE-AUDIT.md, groups gaps into logical phases, creates phase entries in ROADMAP.md, and offers to plan each phase.
One command creates all fix phases — no manual /gad:add-phase per gap.
@workflows/plan-milestone-gaps.md
**Audit results:**
Glob: .planning/v*-MILESTONE-AUDIT.md (use most recent)
Original intent and current planning state are loaded on demand inside the workflow.
Execute the plan-milestone-gaps workflow from @workflows/plan-milestone-gaps.md end-to-end.
Preserve all workflow gates (audit loading, prioritization, phase grouping, user confirmation, roadmap updates).
