node-26#9. decoder_control.py's AIS mode now actually launches AIS-catcher
instead of 400ing: a background thread reads its stdout JSON stream
(one message per line) and keeps a live in-memory snapshot keyed by mmsi,
since AIS-catcher streams rather than writing a periodic file the way
dump1090's --write-json does. Messages are merged onto the existing entry
per mmsi rather than replacing it, since AIS-catcher emits static data
(name) and position reports (lat/lon) as separate message types — a naive
overwrite would blank the name back to null on every position-only update
(caught by a standalone unit check against a fake stdout stream before
this fix, not by pytest — this container has no test suite yet).

edge-node's telemetry_uplink_loop now posts non-empty vessel snapshots to
the new /telemetry/ais the same way it already does for aircraft.

UNVERIFIED against real hardware/binary in this session, same caveat as
the ADS-B commit — AIS-catcher's JSON field names are believed correct
from its docs, not confirmed against a real capture.

Logan CusanoandClaude Sonnet 5 b2e3804dc3 Wire ADS-B end to end: secondary-sdr container running dump1090 
node-26#9. New secondary-sdr-container claims the node's SECOND physical
SDR (RTL-SDR index 1 — op25 always claims index 0; no serial-based binding
yet, same gap op25 itself has). Its control API (start/stop/status/data,
mirroring op25_controller.py) launches dump1090 in adsb mode and exposes
the decoded aircraft.json snapshot; AIS mode 400s until it's wired next.

edge-node: on_config_push starts/stops it when secondary_sdr_mode changes,
lifespan resumes it after a restart if already configured, and a new
telemetry_uplink_loop polls its /secondary/data every 10s and POSTs
non-empty snapshots to C2's new /telemetry/adsb (same bearer-key pattern
call_recorder.py already uses for audio upload).

UNVERIFIED: this container has not been built or run against real hardware
in this session (sandboxed authoring machine, no docker) — dump1090's
--write-json field names are believed correct from its docs but not
confirmed against a real capture. Build + hardware smoke test before this
reaches a real node.

Logan CusanoandClaude Sonnet 5 8f5fca8757 Add second-SDR plumbing: secondary_sdr_mode config + hardware reporting 
Adds a per-node secondary_sdr_mode config field (none|adsb|ais|op25_2),
applied the same way as hardware_preset/ppm_override so it survives system
reassignment. op25-container gets a GET /devices endpoint that counts
connected SDRs via lsusb; the edge-node checkin now reports sdr_count and
secondary_sdr_mode up to the server, the first node-initiated hardware
report (everything else was C2 pushing config down). Tracked as node-26#9.
