Passive CANopen listener for the E380 (no bus writes; coexists with open3e). Pinned V0.5.2, 10 s per-DID throttle, JSON payloads under the open3e/ topic prefix with the shared broker user. Already deployed and verified on edge-1 alongside open3e. Counterpart HA PR adds the 14 sensors.

edge-host: E3onCAN service — read the E380 meter directly 384bd54e8b

Passive listener (no bus writes, coexists with the single open3e
instance) decoding the E380's own CANopen broadcasts: per-phase active/
reactive power, currents + cosPhi, voltages + grid frequency, and the
meter's cumulated import/export counters — instead of trusting the
VX3's relayed values. Pinned to V0.5.2; ~5 Hz broadcasts throttled to
one MQTT update per DID per 10 s; JSON payloads under the open3e/
prefix with the shared broker user.
