Phase 8's mechanical part. The 19 asyncio.get_event_loop() calls that run directly in an async def (found by walking each file's AST; calls inside nested sync functions or lambdas don't count) become asyncio.get_running_loop(). Inside a running coroutine both return the same loop; get_running_loop says so and never creates one. The five calls in sync functions (maintenance.run_data_retention, radio_link._handle_serial_probe_error, scheduler._run_in_current_loop and run_scheduler, weather_service._run_daily_forecast) can run on threads without a loop, where the two differ, so they stay. No test patches get_event_loop.
- Implemented functionality to prevent Discord mention notifications for `@everyone`, `@here`, roles, and users when relaying messages from MeshCore.
- Added a new method to neutralize Discord mention content, ensuring that mentions are displayed as plain text without triggering notifications.
- Updated the Discord webhook payload to include `allowed_mentions` settings to suppress mention parsing.
- Enhanced tests to verify the correct behavior of mention neutralization and webhook payload structure.
Add bridge_outbound posting, BaseServicePlugin.send_external_notifications,
and RepeaterPrefixCollision discovery vs collision routing with silence_mesh_output.
