Biomekka 1.8.30
================

Base
----
Built from Biomekka 1.8.29.

Added
-----
- ESP-side Agent DVR storm clip trigger.
- Fires only after 60 seconds of the full storm phase.
- Does not fire during pre-storm.
- Calls the Ubuntu wrapper endpoint:
  http://***:8099/biomekka/storm-record?camera=top&seconds=30
- Intended behaviour: wrapper records the Agent DVR top camera for 30 seconds.
- Top camera only; no bottom camera support added.
- Trigger is one-shot per storm.
- If WiFi is down at the 60 second point, it retries every 15 seconds until the storm ends or it sends the request.
- HTTP timeout kept short at 1.8 seconds so the controller is not stuck waiting around.
- Feature can be disabled with AGENT_STORM_RECORDING_ENABLED.

Notes

This only adds the ESP trigger. The Ubuntu wrapper endpoint still needs to exist and handle start/stop recording in Agent DVR.
