Independent monitor + checker for CHANGE_CURRENT_LD1 variation, where the
board sweeps LD1 current autonomously while both laser temperatures must stay
on their static setpoints. Nothing previously verified that the setpoints were
actually reached, so a stale temperature silently corrupted measurements.
New package python_app/hardware_full/laser_control/monitoring/:
- session.py: LaserVariationSession snapshot (targets + tolerance frozen at start)
- readings_channel.py: JSONL append/tail channel for per-sweep readings
- monitor.py: LaserTemperatureMonitor polls the board once per sweep, publishes
- checker.py: LaserTemperatureChecker validates temp1/temp2 vs targets (0.03 C),
warns to console per laser with anti-spam state
CLI entry points scripts/laser_temp_monitor.py and scripts/laser_temp_checker.py
run as independent processes communicating via IPC files.
Also: add temp_tolerance_c to LaserVariationModeModel (schema + codec round-trip)
and write the session snapshot from apply_kamil_adc_laser_control's variation path
so the checker works with pipeline-started runs too.
Tests in tests/test_laser_temp_monitoring.py (17 cases); existing laser-control
protocol and config-codec suites remain green.
