feat: Add Adafruit Feather ESP32-S3 Reverse TFT board support

- Add new board environments: adafruit_feather_esp32s3_reversetft,
  adafruit_feather_esp32s3_reversetft_rtos, and test_feather_reversetft
- Update README.md to reflect tri-board support with build instructions
- Add new board option in hardware requirements section
- Update documentation badges and references to include reverse TFT

Technical improvements:
- Fix latency test session restart issues in RTOS mode
- Improve WiFi mode switching with RTOS-aware delays
- Enhanced serial communication robustness in command processing
- Add debugging commands for RTOS task monitoring

Build verification:
- All new environments compile successfully
- RAM usage: 16.1-16.2%, Flash usage: 72.1-75.0%
- Full NeoPixel and web server support maintained
