Note

Adds a shared messaging transport and routes extension subscription responses to it, enables webInterferenceDetection and breakageReporting on Firefox, updates breakage reporting to use detector settings, and cleans up detector docs/config.

• Messaging
  • Introduces shared singleton SendMessageMessagingTransport with getSharedMessagingTransport() and uses it in extensionConstructMessagingConfig().
  • Routes extension subscription responses (messageType) from injected/entry-points/extension-mv3.js to transport.onResponse() so all subscribed features receive them.
• Features
  • Enables webInterferenceDetection and breakageReporting on firefox in injected/src/features.js.
  • breakage-reporting now reads detector settings from webInterferenceDetection (interferenceTypes) and runs botDetection/fraudDetection.
• Docs/Cleanup
  • Updates injected/src/detectors/README.md to document config/architecture; removes obsolete injected/src/detectors/default-config.js.
