ROS Parameter Changes

Parameter Name	Default Value	Update Description
`obstacle_velocity_threshold_from_cruise_to_stop`	`1.0 m/s`	Lowering the this threshold below `obstacle_velocity_threshold_from_stop_to_cruise` to prevent chattering between cruise and stop
`obstacle_velocity_threshold_from_stop_to_cruise`	`1.5 m/s`	Lowering the the velocity threshold hysteresis from cruise to obstacle stop so that `obstacle_cruise_planner` is not performing high -ve acceleration once the VRU is overlapping with ego trajectory and allowing the ego vehicle to cruise the front VRU not always triggering obstacle stop for it

Effects on system behavior

Enhancing the obstacle_cruise_planner to effectively handle scenarios where vulnerable road users (VRUs) suddenly maneuver and overlap with the ego vehicle's trajectory in dense urban operational design domains (ODDs) will improve deceleration and velocity adjustments, resulting in more human-like driving behavior.
