Major Updates

Breaking Changes

The SDK package was renamed from airbot_py to arm_sdk, and its main class from AIRBOTArm to AirbotClient.
The control-mode system was restructured: the RobotMode enum was replaced with the Controller enum (direct_control / servo_control / planning_control / mit_control), with modes switched through switch_controller().
Motion-control interfaces were renamed: move_to_joint_pos → move_joint, move_to_cart_pose → move_end_pose, and move_with_*_waypoints → move_joint_waypoints / move_end_pose_waypoints.

New Features

Added an exclusive Lease-based control-ownership mechanism (acquire_control() / release_control()) to prevent control conflicts between multiple clients.
Added Cartesian-space linear trajectory planning (move_end_pose_linear()) and circular trajectory planning (move_end_pose_circle()).
Added the unified ArmControlOptions class for centralized management of speed, current, planning, and other parameters.
Added firmware-information queries (get_firmware_info()), arm emergency stop (set_arm_emergency_stop()), return-to-zero (return_zero()), and motor-error clearing interfaces.
Added set_arm_speed() to replace set_speed_profile(), with per-joint maximum-speed configuration.
