## Summary
This PR updates the C++ hardware interface to support **CANFD** and confirms successful operation with **MoveIt** on the actual robot hardware.
---
## Changes Made
- Migrated from classic CAN to **CANFD** in the motor control interface.
- Updated the following modules:
- `openarm_hardware/include/openarm_hardware/canbus.hpp`
- `openarm_hardware/src/canbus.cpp`
- `openarm_hardware/src/motor_control.cpp`
- `openarm_hardware/include/openarm_hardware/motor_control.hpp`
- `openarm_hardware/src/openarm_hardware.cpp`
- Improved CAN socket handling and data frame structure.
- Refactored internal motor communication logic for robustness.
---
## Verification
- Confirmed joint control and motion execution with real hardware using **MoveIt**.
- Controllers were properly loaded and executed planned trajectories without error.
- CANFD communication is now functional and stable during runtime.
