Meisoftcoltd 4d18b4e69d Implement Seed Mutator in SequentialLoopTrigger to break ComfyUI cache
- Replaced existing SequentialLoopTrigger logic.
- Added dictionary scanning to intercept the queue POST JSON payload.
- Injects a new 32-bit random integer (`0xffffffff` max) into any node possessing `seed` or `noise_seed` in its inputs.
- Preserves the sequential auto-queue logic but now guarantees the sampler processes a new generation instead of instantly returning cached results in subsequent loops.
