Muse Minimax Director V1.2

Timeline-based director node for MiniMax H3 — visual CUT/segment editor, multi-character reference images, reference video + reference audio (with per-clip audio pairing for lipsync/voice reference), First/Last Frame mode, automatic chunking, two-stage sampling, a VAE re-encode continuity mode that hard-freezes a real re-encoded window of the previous chunk's output across the chunk boundary, and an explicit Seed Hunt on/off switch with a 1-4 candidate count. Bundled with its companion Muse Minimax Refine node — picks one Seed Hunt candidate and continues its sigma schedule at a higher resolution, including full multi-chunk Latent-Only Scouting candidates, not just a single chunk.
