Meisoftcoltd 1e36f9e915 feat: implement VRAM defragmentation strategy and optimization ...

- Created `MeisoftVRAMDefragmenter` in `vram_node.py` as a passthrough to force model unloading, Python garbage collection, and CUDA cache defragmentation.
- Registered the new node in `__init__.py`.
- Added light memory cleanup on intermediate batch loops in `loop.py`, alongside a heavy cleanup (including ctypes `malloc_trim`) at the end.
- Added `unload_detector_after_analysis` boolean flag to `VideoAnalyzerWithAudio` in `video.py` to allow releasing the BBOX detector model immediately after use.
