Refine .gitignore patterns for .vscode directory

Reorganize .gitignore to explicitly allow settings.json:

- Move .vscode pattern to maintain alphabetical order
- Add negation pattern to explicitly allow .vscode/settings.json
- Other .vscode files (launch.json, workspace files, etc.) remain ignored

This makes it clear that settings.json is intentionally tracked while
other IDE-specific files are ignored.
