Wraps an async operation with a timeout, rejecting with TimeoutError if it exceeds the limit.

Accepts either a Promise or a factory function that returns a Promise. The timer is cleaned up on both success and failure to prevent memory leaks. Used throughout AgentRuntime for tool execution timeouts, approval wait timeouts, and MCP request timeouts.
