 * `@safe` decorator: wraps a method or getter in try/catch and returns a fallback value on synchronous error.
 * - Supports static or provider fallback (ValueOrProvider)
 * - Invokes instance hook `$$error(error, name, original)` before returning fallback
 * - Only handles synchronous throws (async rejections pass through)
 *
 * @param fallback - value or provider used when the original function throws (default: null)
 * @throws Error when applied to a non-function / non-getter
