refactor: extract LAMMPS language definition from Edit.tsx

[andeplane]

Summary

Extracts the LAMMPS Monaco language definition from Edit.tsx into a separate module, significantly reducing the file size and improving maintainability.

Changes

• Created src/utils/lammpsLanguage.ts: Contains ~1,200 LAMMPS keywords and Monaco Monarch tokenizer configuration
• Updated src/containers/Edit.tsx: Reduced from 1,458 LOC to 56 LOC (96% reduction)

Benefits

• Clear separation of concerns: language definition is now isolated
• Improved maintainability: language keywords can be updated independently
• Better code organization: React component is now focused solely on editor rendering
• Type-safe: Proper TypeScript types for Monaco instance compatibility

Testing

• ✅ All existing tests pass (213/213)
• ✅ TypeScript compilation successful
• ✅ No linter errors

Summary of Changes

Hello @andeplane, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a significant refactoring effort to improve the architecture and maintainability of the application's Monaco editor integration. By extracting the large LAMMPS language definition into its own module, the core editor component becomes much leaner and easier to manage, promoting better code organization and a clearer separation of responsibilities.

Highlights

• Code Extraction: The extensive LAMMPS language definition, including approximately 1,200 keywords and the Monaco Monarch tokenizer configuration, has been extracted from src/containers/Edit.tsx into a new dedicated module: src/utils/lammpsLanguage.ts.
• File Size Reduction: The src/containers/Edit.tsx file has been significantly reduced from 1,458 lines of code to just 56 lines, representing a 96% reduction in its size and complexity.
• Improved Modularity and Maintainability: This refactoring establishes a clear separation of concerns, allowing the language definition to be updated independently and improving the overall organization and maintainability of the codebase. The React component (Edit.tsx) is now solely focused on editor rendering.
• Type Safety: The new module ensures proper TypeScript types for Monaco instance compatibility, enhancing code robustness.

Code Review

This is an excellent refactoring that significantly improves the codebase. Extracting the large LAMMPS language definition from the Edit.tsx component into its own module (lammpsLanguage.ts) is a great move for separation of concerns and maintainability. The Edit.tsx component is now much cleaner and focused on its rendering responsibilities.

I've found a couple of areas for improvement in the new lammpsLanguage.ts file. One is a correction to the comment syntax highlighting to match the LAMMPS language specification, and the other is a suggestion to improve the maintainability of the keyword list. Please see the detailed comments.

This large list of keywords is unsorted, which makes it difficult to maintain. It's hard to check for duplicates or determine if a keyword is already in the list. Sorting these keywords alphabetically would greatly improve readability and maintainability.
