    Flash the monitor firmware (UWB monitor, 2MB flash, app at 0x10000).

    Reads monitor/flasher_args.json for the chip, flash settings and the exact
    file -> offset map, auto-detects the serial port, and refuses to overwrite a
    partition table in a way that would lose data on the board.

    Examples:
        .lash_monitor.ps1                # flash bootloader + partition table + app
        .lash_monitor.ps1 -DryRun        # show what would happen, write nothing
        .lash_monitor.ps1 -AppOnly       # write only the app, keep board data
        .lash_monitor.ps1 -Monitor       # flash, then open the serial monitor
        .lash_monitor.ps1 -Port COM12    # force a port
        .lash_monitor.ps1 -ManualBoot    # board put into download mode by hand (BOOT+RESET)
        .lash_monitor.ps1 -List          # just list candidate serial ports
