Groom Milestone

Prepare a GitHub milestone for parallel execution by /work-milestone.

Outcome

All items in the milestone are groomed, dependency-analyzed, and conflict-grouped — producing a dispatch plan that /work-milestone can execute without further human input except blocker resolution.

Entry Conditions

• Milestone number provided as first argument
• Milestone exists on GitHub with state=open
• At least one item assigned to the milestone (via /group-items-to-milestone)
• Backlog MCP server responding
