Pull request overview

Updates the bundled TinyUSB stack to align with upstream v3.7.3, adding/refreshing multiple class drivers and modernizing the Adafruit ArduinoCore integration layer.

Changes:

• Syncs in additional/updated TinyUSB class driver headers/sources (CDC host/device, DFU, MSC host, MIDI host/device, HID host, networking, BTH, Audio).
• Refactors Adafruit ArduinoCore abstractions (USBD device/interface/CDC) and adds a dedicated port API + nRF implementation.
• Adjusts CI dependency resolution (PlatformIO platform source) and removes the legacy README.
