sl-controls a50f22d56b feat: Nav2 cmd_vel to STM32 autonomous drive bridge

Adds cmd_vel_bridge_node — a standalone ROS2 node that subscribes to
Nav2 /cmd_vel and drives the STM32 over USB CDC with:
  - Hard velocity limits (max_linear_vel=0.5 m/s, max_angular_vel=2.0 rad/s)
  - Smooth ESC ramp (500 ESC-units/s, 50 Hz control loop)
  - Deadman switch: zeros targets if /cmd_vel silent >500 ms
  - Mode gate: sends drive only when STM32 reports md=2 (AUTONOMOUS)
  - Telemetry RX → /saltybot/imu, /saltybot/balance_state, /diagnostics
  - Heartbeat TX every 200 ms (H\n)

Deliverables:
  saltybot_bridge/cmd_vel_bridge_node.py   — node implementation
  config/cmd_vel_bridge_params.yaml        — tunable parameters
  launch/cmd_vel_bridge.launch.py          — standalone launch file
  test/test_cmd_vel_bridge.py              — 37 pytest unit tests (no ROS2)
  setup.py                                 — register node + new data files
