Plot: Deliver Plan

Verify all implementation is done, then deliver the plan. This workflow can be run manually (using git and forge CLI), by an AI agent interpreting this skill, or via a workflow script (once available).

For docs/infra work, this is the end — live when merged. For features/bugs, /plot-release follows when the team is ready to cut a versioned release.

Input: $ARGUMENTS is the <slug> of a plan on main.
