Strycher	ea4adb3faa	fix(#248 ): VID-gate the USB DTR open pulse (don't wedge ESP32-C6) The DTR low→high pulse in the desktop USB open path resets ESP32 USB-Serial/JTAG chips (VID 303A: C6/H2/S3-HWCDC) into ROM download mode mid-handshake, wedging the device until a physical reset. The pulse exists for nRF52 (VID 239A) reconnect-after-unclean-disconnect, so it can't just be removed. connect() now recovers the port's USB VID from the flserial enumeration (hardware_id) and gates the pulse: 239A keeps the DTR low→high pulse; 303A and any unknown/unparseable VID open with DTR asserted and no pulse. VID lookup is enumeration-only (never opens the port). New usb_vid helper parses both flserial hardware_id formats (Windows VID_XXXX and macOS/Linux VID:PID=xxxx:xxxx), unit tested. Build of epic #245.	1 week ago

fix(#248 ): VID-gate the USB DTR open pulse (don't wedge ESP32-C6)

The DTR low→high pulse in the desktop USB open path resets ESP32 USB-Serial/JTAG
chips (VID 303A: C6/H2/S3-HWCDC) into ROM download mode mid-handshake, wedging
the device until a physical reset. The pulse exists for nRF52 (VID 239A)
reconnect-after-unclean-disconnect, so it can't just be removed.

connect() now recovers the port's USB VID from the flserial enumeration
(hardware_id) and gates the pulse: 239A keeps the DTR low→high pulse; 303A and
any unknown/unparseable VID open with DTR asserted and no pulse. VID lookup is
enumeration-only (never opens the port). New usb_vid helper parses both flserial
hardware_id formats (Windows VID_XXXX and macOS/Linux VID:PID=xxxx:xxxx), unit
tested. Build of epic #245.
