milestone-workflow

Use when the user wants a milestone of Execution-block-stamped GitHub issues implemented via a multi-agent dynamic workflow: "create the workflow for v0", "run v0 continuously", "/milestone-workflow v0". Builds tracks, gets the run plan approved, runs the milestone-pipeline workflow to LGTM PRs, merges them in-session, and releases when every issue merges. Stage 7 of the new-app-pipeline.
