Match the OLLAMA_URLS pattern from zerto-docs-rag so every docs MCP
build fans out across the same two GPU-pinned Ollama containers on
192.168.0.2 (:11435 Titan X, :11436 1080 Ti). The host's primary
Ollama on :11434 is left alone for OpenWebUI.
rag.embeddings now reads OLLAMA_URLS (plural CSV) preferentially with
fallback to OLLAMA_URL, defaulting to http://192.168.0.2:11434 — same
shape as zerto's embeddings.py. The OllamaEmbeddings class already
round-robins per batch, so both GPUs run in parallel during the
chroma rebuild.
