📝 Walkthrough

Walkthrough

The PR changes workspace/document resolution to prefer the language server’s in-memory documents: createLanguageServerAdapter now accepts a LanguageServer and readFile checks server.documents before falling back to disk. The language-service gains a new utils/document.ts exporting getDocumentByUri and getResolvedDependencyAtOffset; callers in catalog, hover and version-completion were updated to import and use these helpers. The workspace wiring and adapter call sites were updated to pass the server, and the workspace package.json/pnpm catalog adds vscode-languageserver-textdocument.
