Note

Adds proxy-based handling when navigator.permissions exists and refactors the shim to use native messaging with safe fallthrough; updates and consolidates tests for both API-present and API-absent scenarios.

• WebCompat (permissions)
  • Introduces permissionsPresentFix to proxy navigator.permissions.query when the API exists, intercepting only configured native permissions and falling through otherwise.
  • Extracts shared PermissionStatus and handlePermissionQuery for native messaging and consistent results; on errors, falls back to original API/defaults.
  • Enhances permissionsFix (API-absent) to reuse shared handler, validate inputs, and support name overrides while returning prompt by default.
• Tests
  • Refactors Permissions API tests with shared setup/utilities and a runner for API-absent cases.
  • Adds "Permissions API - when present" suite covering fallthrough to original API, native interception, name overrides, invalid args, and native failure behavior.
  • Keeps existing Notification and ScreenOrientation tests intact; minor setup cleanups.

Changes look good, but it might be worth updating the integration tests? We have some basic ones for permissions APIs already.
