plan-review-worktree-delivery

Use when a requirement is ready for implementation and you want every task to begin by creating a git worktree, then have @Prometheus draft the plan, @Momus critique it until approval, save the approved plan in the repository, and implement inside that worktree. Supports repositories with or without git submodules, including submodule-aware planning, submodule initialization in the worktree, and a required stop point immediately after implementation with a complete report of every exact revision, branch-or-detached state, and worktree used.
