Add PowerStatusV2 (40 B, version byte = 2) with offset-checked decode and a known-bytes round-trip test that locks the wire layout. The dispatcher branches on the payload version byte and down-converts v2 -> PowerStatusV1 for storage (host stays v1-native for now), so the strict decoder no longer rejects v2 frames emitted by the CH32X.

Why
The firmware now emits
power.statusv2 (40-bytewups_power_status_v2_t, version byte = 2) — merged inWeb3-Pi-UPSPR #3 (2026-06-21). The agent onmain(e58083a) runs the v1-strictcheck_version()and rejects any frame whose version byte ≠ 1, so a Pi running an agent built frommain/release v2.0.1 would drop all UPS telemetry from v2 firmware — leaving the safe-shutdown logic blind to battery state.This branch (
fe4e768) adds the matching v2 decoder.What
