Adds saltybot_bridge_msgs package with WheelTicks.msg (int32 left/right
encoder counts) and a WheelOdomNode that subscribes to
/saltybot/wheel_ticks, integrates midpoint-Euler differential drive
kinematics (handling int32 counter rollover), and publishes
nav_msgs/Odometry on /odom_wheel at 50 Hz with optional TF broadcast.
New files:
jetson/ros2_ws/src/saltybot_bridge_msgs/
msg/WheelTicks.msg
CMakeLists.txt, package.xml
jetson/ros2_ws/src/saltybot_bringup/
saltybot_bringup/_wheel_odom.py — pure kinematics (no ROS2 deps)
saltybot_bringup/wheel_odom_node.py — 50 Hz timer node + TF broadcast
test/test_wheel_odom.py — 42 tests, all passing
Modified:
saltybot_bringup/package.xml — add saltybot_bridge_msgs, nav_msgs deps
saltybot_bringup/setup.py — add wheel_odom console_script entry
