-When starting any file-changing task, use a dedicated git worktree by default. This is required whenever parallel agent work may happen in the repository.

 When the change is ready, fast-forward the shared checkout at `../herdr` to the task branch commit, then push `origin/master` from `../herdr`. Do not treat the task branch as the final landing branch.
