cleanup: Remove all Mamba/STM32/BlackPill references — ESP32-S3 only
- Renamed mamba_protocol.py → balance_protocol.py; updated all importers
- can_bridge_node.py rewritten to use balance_protocol.py API (ESP32-S3 BALANCE)
- test_can_bridge.py rewritten to test actual balance_protocol.py constants/functions
- All STM32/Mamba references in Python, YAML, Markdown, shell scripts replaced:
* Hardware: MAMBA F722S → ESP32-S3 BALANCE/IO
* Device paths: /dev/stm32-bridge → /dev/esp32-io
* Node names: stm32_serial_bridge → esp32_io_serial_bridge
* hardware_id: stm32f722 → esp32s3-balance/esp32s3-io
- C/C++ src/include/lib/test files: added DEPRECATED header comment
- Covers: saltybot_bridge, saltybot_can_bridge, saltybot_can_e2e_test,
saltybot_bringup, saltybot_diagnostics, saltybot_mode_switch, and all
chassis, docs, scripts, and project files

feat(firmware): Jetson binary serial protocol on USART1 (Issue #120)
New jlink module replaces ASCII-over-USB-CDC jetson_cmd with a dedicated
hardware UART binary protocol at 921600 baud for reliable Jetson comms.
- include/jlink.h: JLinkState struct, jlink_tlm_status_t (20-byte packed),
command/telemetry IDs (0x01-0x07 cmd, 0x80 status), API declarations
- src/jlink.c: USART1 DMA2_Stream2_Channel4 circular RX (128 bytes),
IDLE interrupt, CRC16-XModem (poly 0x1021) frame parser state machine,
command dispatch (HEARTBEAT/DRIVE/ARM/DISARM/PID_SET/ESTOP),
jlink_send_telemetry() blocking TX (≈0.28 ms per frame)
- include/config.h: JLINK_BAUD=921600, JLINK_HB_TIMEOUT_MS=1000,
JLINK_TLM_HZ=50, FW_MAJOR/MINOR/PATCH version constants
- src/main.c: jlink_init(), jlink_process() in main loop, arm/disarm/
estop/PID flag handling, 50 Hz STATUS telemetry TX, jlink takes
priority over legacy jetson_cmd for speed/steer injection
- test/test_jlink_frames.py: 39 pytest tests (39/39 pass) — CRC16,
frame building, parser state machine, drive/PID/status encoding
