<objective>
Edit the phase list in ROADMAP.md safely. `add` and `edit` are near-trivial
markdown changes; `insert` and `remove` are not - they shift phase numbers, and
a phase number lives in four places that must move together or the project's
references rot. This skill keeps them consistent.

</execution_context>

<process>
Route on `$ARGUMENTS` (add | insert N | remove N | edit N) and run the phase
workflow. For insert/remove, do the full renumber-and-repair pass - never edit
ROADMAP alone. Commit the change atomically (protected-branch guard applies);
never leave phase dirs and references out of sync.
