Deprecate MATLAB implementation — move all future development to Python

[ContinuumRoboticsLab]

• Add a clear note in the MATLAB subdirectory’s README indicating that it is no longer actively developed.
• Update the main project README to state that Python is the primary and actively maintained implementation.
• Optionally, add a warning message or banner in the MATLAB codebase (e.g., a startup message) noting its deprecated status.
• Ensure contributors are aware that new pull requests should only target the Python implementation.
