// Step 1913: LSPWorkspaceIndex
// Tracks open LSP documents: URI → {languageId, content, version}.
//
//  t1: open and contains
//  t2: getLanguage and getDocument
//  t3: update changes content and version
//  t4: listUris filters by languageId
//  t5: close removes document; allLanguages reflects current set
