Support double‑clicking MATLAB-related files in VS Code Explorer

Is your feature request related to a problem? Please describe.
Currently, MATLAB‑related files (.mat, .fig, .slx, .mdl, .mlapp, .mlx, and other extensions) cannot be opened in the same way as in MATLAB Desktop’s File → Workspace. In VS Code Explorer, double‑clicking these files only shows them as binary files and they cannot be opened.

Describe the solution you'd like
I would like the behavior to be similar to MATLAB Desktop:

• Double‑clicking a .mat file should directly import the data into the MATLAB Workspace.

• Double‑clicking a .fig file should open the figure window.

• Double‑clicking a .mlapp file should open the App Designer interface.

• … and so on.

Describe alternatives you've considered
At present, I can only open these files by explicitly calling MATLAB built‑in functions such as load or open, alternative, I install another mathworks' extension https://github.com/mathworks/data-explorer-vscode

The issue names no files or tests; begin by locating how the extension handles VS Code Explorer file opening and review the listed MATLAB extensions. Done means the requested double-click behaviors work for .mat, .fig, and .mlapp files, with equivalent handling for the remaining supported formats.
