Consumes `compileMorfo(morfo).contracts.cssSelectors` to classify every
`[data-*]` selector in an eidos CSS file:
- morfo-backed: the runtime writes the attr; eidos reacts to it.
- eidos-only: the marker is present (`[data-toggle]`) but at least
one `data-*` is not declared on the morfo part. Legitimate design
tokens (`data-color`, `data-size`, `data-variant`) and drift cases
(`data-dialog-header` — a part the morfo no longer declares) both
land here; the lint tool reports them so authors can decide.
- invalid: the attr IS declared on the morfo, but with a value
outside the declared enum. Bug.
Also reports `unusedFromContract`: selectors the compiler promises
that no eidos rule consumes — the inverse direction of drift.
Two CLI entry points:
- `scripts/eidos-lint.ts <component>` — single-component report
- `scripts/eidos-lint-all.ts` — sweep across every eidos component
Initial sweep finds 0 invalid, 134 eidos-only, 82 unused contract
selectors across 11 components. Real drift hotspots: dialog/drawer
`header`/`footer` (eidos parts the morfos don't declare), popover's
`data-side × data-last-action` compounds, tooltip's
`data-state='delayed-open'`. Deliberate left as-is for the user to
triage — fixes belong in a separate commit.
Tests cover toggle (clean baseline), dialog (drift detector for
header/footer + dead `data-disabled`), and a synthetic invalid case.
