decoder: broadcast frames to yukart/vehicle/* from contracts' can blocks

Kernel-filtered read-only socket; booleans on change, numbers <= 20/s, every live value refreshed once a second, stale after 1 s of silence. --replay runs a candump log through the same path, --list prints the layouts. obd-poller drops engine_rpm, now a z27ag signal.

+Description=Yukart decoder: the car's broadcast CAN frames to named signals on the bus
+Documentation=gitea:yukart/svc-core
+# Tier 2. Ordered after the broker and nothing else: the adapter comes and goes, and
+# the decoder reopens the interface by itself. It only reads the bus.
