mikkeli 1f678fe87f Add recorder: raw CAN and GNSS sessions with failsafes and a storage bound
Reads SocketCAN and gpsd directly. Sessions start on the first frame or on
'ctl start', end after 15 s of bus idle or on 'ctl stop'; blips under 3 s are
discarded. candump -L chunks fdatasync'd every second and zstd'd once closed;
oldest sessions deleted to stay under 50 GB / above 20 GB free. Kernel and
queue drops, link changes and clock steps are recorded as events.

Bench-tested on vcan with the first car capture (byte-identical) and installed
on the car Orin as yukart-recorder.service.

What this repo is about

The acquisition and processing cluster on the Orin, developed and deployed as one unit: recorder now; can-bridge, obd-poller, gnss and decoder as they are needed.

Binary Installed as Does
recorder yukart-recorder.service Raw CAN + GNSS to disk, in sessions, under a storage bound
scripts/deploy-recorder.sh                 # build, glibc check, install on the car Orin
yukart-recorder ctl status                 # on the Orin
yukart-recorder ctl start "cold start"     # manual session, ends only on stop
yukart-recorder ctl mark "indicator left on"
yukart-recorder ctl stop

Recordings live in /var/lib/yukart/recordings/, one directory per session — layout in the initial plan.
