sl-firmware 291dd689f8 feat: remove all STM32/Mamba/BlackPill references — ESP32-S3 only
Archive STM32 firmware to legacy/stm32/:
- src/, include/, lib/USB_CDC/, platformio.ini, test stubs, flash_firmware.py
- test/test_battery_adc.c, test_hw_button.c, test_pid_schedule.c, test_vesc_can.c, test_can_watchdog.c
- USB_CDC_BUG.md

Rename: stm32_protocol → esp32_protocol, mamba_protocol → balance_protocol,
  stm32_cmd_node → esp32_cmd_node, stm32_cmd_params → esp32_cmd_params,
  stm32_cmd.launch.py → esp32_cmd.launch.py,
  test_stm32_protocol → test_esp32_protocol, test_stm32_cmd_node → test_esp32_cmd_node

Content cleanup across all files:
- Mamba F722S → ESP32-S3 BALANCE
- BlackPill → ESP32-S3 IO
- STM32F722/F7xx → ESP32-S3
- stm32Mode/Version/Port → esp32Mode/Version/Port
- STM32 State/Mode labels → ESP32 State/Mode
- Jetson Nano → Jetson Orin Nano Super
- /dev/stm32 → /dev/esp32
- stm32_bridge → esp32_bridge
- STM32 HAL → ESP-IDF

docs/SALTYLAB.md:
- Update "Drone FC Details" to describe ESP32-S3 BALANCE board (Waveshare ESP32-S3 Touch LCD 1.28)
- Replace verbose "Self-Balancing Control" STM32 section with brief note pointing to SAUL-TEE-SYSTEM-REFERENCE.md

TEAM.md: Update Embedded Firmware Engineer role to ESP32-S3 / ESP-IDF

No new functionality — cleanup only.
