LSP File Lifecycle Management

What: Four new methods for synchronizing file state with Language Server Protocol servers How to use:

// These methods are called automatically by Claude Code's LSP integration
// Manual use in custom integrations:
const lspManager = createLSPManager();
await lspManager.initialize();

// Notify server when opening a file
await lspManager.openFile('/path/to/file.js', fileContent);

// Sync content changes
await lspManager.changeFile('/path/to/file.js', newContent);

// Notify server when closing
await lspManager.closeFile('/path/to/file.js');

// Inspect available servers
const servers = lspManager.getAllServers();

Details:

• getAllServers() returns Map of all initialized LSP servers for monitoring
• openFile(path, content) sends textDocument/didOpen with proper languageId mapping
• changeFile(path, content) sends textDocument/didChange, falls back to openFile if server not running
• closeFile(path) sends textDocument/didClose for cleanup
• Configuration changed from fileExtensions array to extensionToLanguage object mapping for proper language ID support
• Better error messages in shutdown that include actual error details instead of generic "check logs"
