fix: template-no-invalid-interactive — honor role=presentation/none and aria-hidden as escape hatches

Premise: peer a11y plugins (jsx-a11y `hasPresentationRole` + aria-hidden
handling inside `isInteractiveElement`; vuejs-accessibility's equivalent)
treat `role="presentation"` / `role="none"` and `aria-hidden`
(boolean / "true" / `{{true}}`) as explicit opt-outs of the interactivity
contract. An element that has opted out via ARIA does not need an
interactive handler check — the handler is authored acknowledging the
element is decorative or hidden from AT.

Conclusion: wire that opt-out into `template-no-invalid-interactive`
before the native/role-based interactivity probe runs.

- Adds `hasNonInteractiveEscapeHatch(node)` covering:
  - `role="presentation"` / `role="none"` (case-insensitive, trimmed,
    first token of a space-separated role list — matches jsx-a11y).
  - `aria-hidden` as bare boolean attribute, the text value `"true"`,
    or the mustache-literal `{{true}}`. `aria-hidden="false"` does NOT
    qualify.
- Visitor short-circuits on escape-hatch hit before computing interactivity.
- Tests: new valid cases for every escape-hatch shape; new invalid
  cases guarding that `aria-hidden="false"` and other roles still flag.
- Audit fixture `tests/audit/no-static-element-interactions/peer-parity.js`
  added to master as evidence of parity. D1 (role=presentation/none) and
  D2 (aria-hidden) divergences previously documented in the Phase-3 audit
  branch are now parity cases in the valid block.

Tracks PR #28 item G1 (escape-hatch awareness across interactive-handler
rules).
