LongCat Video Avatar 1.5 — MLX Cider pack

Accepted prepared cider_ship checkpoint for Natively Engine. This is an optional native accelerator format, not the portable INT8 default. The DMD LoRA is already merged. Tensor bytes are unchanged from the recorded preparation and acceptance run; see release-manifest.json for checksums and conversion lineage.

Use the matching Natively Engine catalog installer. Shared VAE, UMT5 tokenizer/text encoder and Whisper weights are downloaded separately by the catalog. The Cider native helper must be built locally following the engine's third_party/cider/BUILDING.md; no native binaries are included here. Recorded accelerator acceptance is Apple M5 / macOS 26 / MLX 0.31.2; this does not establish all-Mac performance.
