MatterEx.IM.EventStore (matter_ex v0.3.1)

In-memory ring buffer for Matter events.

Each device gets one EventStore GenServer. Events have a monotonically increasing event number (global across all clusters) and a priority (debug/info/critical). When the buffer is full, lowest-priority events are evicted first.
