## Problem
When we launch openarm_bringup, the following error are raised.
```console
$ ros2 launch openarm_bringup openarm.launch.py

## Cause
when the license comments appeared before the
xml-model instruction, it happedned.
## Solution
This PR changes places the xml-model declaration
immediately after the XML prolog and ahead of the
license block to resolve the issue.
We are standardizing our software under Apache License 2.0. This PR
replaces existing BSD 3-Clause License with Apache 2.0 in this

## How it was done
We added the new license header directory by directory, with each commit
covering a single directory to make review easier.
To ensure there are no missing files, we ran the following commands.
```
$ grep -RIL --exclude-dir='.git' --exclude='*.stl' "Apache License, Version 2.0" .
./openarm_bringup/README.md
./openarm_bimanual_moveit_config/README.md
./openarm_bimanual_description/urdf/openarm_bimanual.urdf
./.gitignore
./README.md
./openarm_description/urdf/openarm.urdf

## 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.
* Create mujoco_ros2_control package
