- Add voyage-context-4, voyage-4, voyage-4-large, voyage-4-lite, and voyage-multimodal-3.5 to the model cost map - Normalize contextual embedding input to list[list[str]] so the contextualized embeddings API is always called with list[str] groups (accepts str and flat list[str] inputs) - Update Voyage provider docs and add tests

Summary
Adds VoyageAI's latest models to the cost map and hardens contextual embedding input handling.
Models added (
model_prices_and_context_window_backup.json)voyage/voyage-context-4— contextual, 120K ctx, $0.12/Mvoyage/voyage-4,voyage/voyage-4-large,voyage/voyage-4-lite— 32K ctx, $0.06 / $0.12 / $0.02 /Mvoyage/voyage-multimodal-3.5— 32K ctx, $0.12/MContextual embeddings input fix
VoyageContextualEmbeddingConfignow normalizes input tolist[list[str]]before calling the contextualized embeddings API. A plainstrbecomes[[str]]and a flatlist[str]becomes a single document[list[str]]; already-nested input is passed through unchanged. Ensures the API is always called withlist[str]chunk groups.Docs
Updated
docs/providers/voyage.md— supported models table, contextual section (now voyage-context-4), and model selection guide.Tests
tests/llm_translation/test_voyage_ai.py— context-4 detection + flat/str input normalization. All 16 pass locally.Reviewer double-checks
list[str]normalized as a single document; confirm that matches intended semantics.
