  Implementation of the "config" tool handler.

  // ── npm config ──
  server.tool(
    "config",
    "View npm configuration (read-only for safety)",
    {
      action: z.enum(["list", "get"]).describe("Action: list (show all config), get (get specific key)"),
      key: z.string().optional().describe("Config key to get (required for get action)"),
    },
    async ({ action, key }) => {
      const args = ["config", action];
      if (action === "get" && key) args.push(key);
      if (action === "list") args.push("--json");
      try {
        const { stdout } = await run(args);
        return { content: [{ type: "text", text: stdout }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
