v0.3.0

Adds the Visitors sensor (sensor.camera_intelligence_visitors): state is the count of known visitors currently on the property, with visitors and details attributes naming each visitor, their vehicle, where seen, and since when.

The push API accepts a visitors list in the snapshot payload (backward compatible — older payloads without it read as 0). Only owner-confirmed known-visitor records are reported; the agent matches unknowns against its known-visitors photo records, never zero-shot guesses.

Update in HACS and restart Home Assistant to load the new sensor.
