Setup Task Tracking

Make the harness's to-do list a standing habit — in force before a task starts, rather than something the user asks for once a task has gone sideways.

Both harnesses already ship the tool: Claude Code TodoWrite, Codex update_plan. Nothing installs them and no setting turns them on — what decides whether they get used is the prose loaded at session start. So this skill installs prose, into the file that is always in context.

That file is the project's agent-facing doc, and the reason is the standing part: rules/*.md load lazily, by paths: glob, once a matching file is touched — by which time the list that should have opened the task is already late. The doc is read before the first move.
