🧠 LTX-2.3 Gemma text encoder — API backend

Private encoder backend for the LTX-2.3 Pre-Production Playground (adapted from linoyts/gemma-text-encoder to LTX-2.3). Runs Gemma-3-12B + the 2.3 embeddings connectors and returns final embeddings (video/audio encodings + attention mask) as a .pt — positive and, when encode_negative=True, negative (for the dev two-stage CFG path). Handles prompt enhancement too. Set HF_TOKEN (gated Lightricks/LTX-2.3).
