Lingua Franca Package Explorer: extensions to UI in VScode plugin

[edwardalee]

This PR proposes extending the Lingua Franca VS Code extension with the following new features:

• Run Button: Add a "Run" button next to the "Display Diagram" button, enabling users to compile and run LF programs directly within the editor.
• Library Reactors Interface: Introduce a user-friendly interface for managing reusable reactor libraries. This allows reactor logic to be defined once and reused across multiple LF projects. Within the VS Code extension, users can access this interface by clicking the LF logo in the activity bar. The interface will feature a tree-view called "Lingua Franca Package Explorer," with two distinct sections:
  • Local Libraries: Displays a catalog of libraries defined by the programmer.
  • Lingo Libraries: Lists all libraries downloaded into the personal workspace via the Lingo package manager.

vinzbarbuto how do you build the extension after merging main? I had problems that I do not have the "lfw-pkg" file. #168

If #171 does not solve your problem, feel free to share the full output that you get when you run npm install.

@vinzbarbuto the PR description still needs to be updated. Please also mark conversations as resolved if they have been addressed fully. Once all conversations are resolved and the description is updated, we can merge this.
