fix(e2e): address final review (allowlist hover_card demo, state-gated locators, docs) master
- hover_card: its 'shown' findings are demo-page artifacts (text-xs muted span, <h4> heading jump in the demo), so allowlist them instead of fixme — this keeps the shown state SCANNED for any other violation. Drop the FOLLOWUPS component entry. - radio_group/slider: return state-gated locators (:checked, :focus, value-changed) so a no-op interaction fails the waitFor instead of scanning the wrong state. - README: correct CI to Tangled (.tangled/workflows/e2e.yml) and Node to 24. (Reviewer's 'command filtered/option-active will fail' was verified false: role= combobox requires aria-expanded, which IS present; aria-controls is not required. Those tests pass — confirmed by running them.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
