/**
 * Task-related errors for MCP 2025-11-25 background tasks.
 *
 * Per spec §Error Handling, task operations MUST use the following JSON-RPC
 * error codes:
 *  - `-32602` (Invalid params): unknown/expired taskId on get/result/cancel,
 *                                attempting to cancel a terminal task,
 *                                invalid cursor on list.
 *  - `-32601` (Method not found): tool-level `taskSupport` violation on
 *                                  a task-augmented `tools/call`, or a
 *                                  non-task-augmented call against a tool
 *                                  whose `taskSupport` is `'required'`.
 *  - `-32603` (Internal error): task subsystem misconfigured (store missing).
