  The handler function for the 'load_project' tool which resolves the path and calls the LSP client's loadProject method.

  async ({ path }): Promise<ToolResult> => {
    try {
      const resolved = resolve(path);
      if (!existsSync(resolved)) {
        return textResult(`Directory not found: ${resolved}`);
      }
      await lsp.loadProject(resolved);
      return textResult(
        `Loaded project '${basename(resolved)}'. Language server is indexing - first requests may be slow.`
      );
    } catch (ex) {
      return textResult(formatError(ex));
    }
  }

• src/tools/lifecycle.ts:18-24 (schema)
