/**
 * 🎯 Decorator `@timeout` enforces a maximum execution time for an async method.
 * If the method does not complete within the specified number of milliseconds,
 * it will be aborted via an `AbortSignal`.
 *
 * Decorator exposes a static property `timeout.signal` that the method can read at runtime.
 *
 * Usage:
 * ```typescript
 * class Example {
 *   @timeout(500) async fetchData(id: string): Promise<Data> {
 *     const { signal } = timeout;
 *
 *     return fetch(`/api/data/${id}`, { signal }).then((r) => r.json());
 *   }
 * }
 *
 * const e = new Example();
 * try {
 *   const data = await e.fetchData("123");
 *   console.log('Got data:', data);
 * } catch (e) {
 *   console.error(e.message); // If over 500 ms: "timeout 500ms exceeded"
 * }
 * ```
