 * Execute an optimized thought delay with interrupt support

 * - Allow time for external processes to complete
 * - Provide natural pacing for complex reasoning
 * - Enable interruption for urgent messages or user input
 *
 * Uses AbortController for clean cancellation.

 * @returns Promise that resolves when delay completes or is interrupted
 *
 * @example
 * ```typescript
 * // Basic delay execution
 * await runThoughtDelay();
 *
 * // With interruption handling
 * try {
