"""Standalone laser temperature monitor process.
Owns the laser serial port, (optionally) starts a current-variation task, then
polls the board once per sweep and appends each reading to a JSONL channel that
the temperature checker tails. Runs until SIGINT/SIGTERM.
Examples::
# Start LD1 current variation from a run config, then monitor:
python -m python_app.scripts.laser_temp_monitor --config run_config.json --start
# Monitor a variation that is already running:
python -m python_app.scripts.laser_temp_monitor --config run_config.json
