feat(v0.4): проводка thermal+coprocessor циклов + D-Bus ThermalState/ThermalChanged + dev-mock

spawn_loops (thermal-монитор + coprocessor heartbeat/wait/safe-to-cut/B09) в main после
регистрации интерфейса; PowerService += thermal_state + хендлы fsm/thermal_state + mock(temp,copro);
dev-mock += SetTemp/HangSoc/McuLinkLoss; proxy.rs += thermal_state/thermal_changed. Existing
integration-тесты подогнаны под mock(temp,copro).
