Add T-Deck device support #824

Summary

Add support for the T-Deck device in the Meshtastic CLI.

Background

The T-Deck is a popular ESP32-based Meshtastic device with a built-in keyboard and display. Currently, the CLI does not recognize T-Deck devices when they are connected via USB.

Proposed Solution

Add T-Deck device definition to supported_device.py with:

• USB vendor ID: 303a (Espressif Systems)
• USB product ID: 1001
• Firmware identifier: t-deck
• Device class: esp32
• Port support for Linux, macOS, and Windows

Testing

• ✅ Device detection working
• ✅ Auto-detection when T-Deck connected
• ✅ Manual port specification
• ✅ All CLI functionality tested
• ✅ No regression in existing device support
