Description

Adds an Open Source tab to the Content Creation Workflow cookbook (docs/cookbooks/operations/content-writing.mdx), giving users a fully local alternative alongside the existing Platform version.

The OSS version uses:

• Mem0 Memory class with Memory.from_config() instead of MemoryClient
• Qdrant (local Docker) as the vector store
• Ollama (llama3.1:latest) for LLM and (nomic-embed-text:latest) for embeddings
• OpenAI SDK pointed at Ollama's /v1 endpoint for content rewriting

Key API differences handled:

• MemoryClient() → Memory.from_config({...})
• client.add() → memory.add() (same signature)
• client.search(query, filters={"AND": [{"user_id": ...}, {"run_id": ...}]}) → memory.search(query, user_id=..., run_id=...) (explicit params instead of filter wrapping)
• openai.chat.completions.create(model="gpt-4.1-nano") → ollama_chat.chat.completions.create(model="llama3.1:latest")

Includes installation section with pip install, Docker, and ollama pull commands, plus a note about swappable embedding models.

Test Coverage

• I added/updated unit tests
• I added/updated integration tests
• I tested manually (describe below)
• No tests needed (explain why)

Tested the OSS cookbook code end-to-end locally with Ollama + Qdrant:

1. Memory.from_config() initialized successfully with Qdrant + Ollama providers
2. memory.add() extracted and stored 6 writing preference memories
3. memory.search() retrieved all 6 preferences correctly
4. Ollama rewrote a sample document applying the stored preferences (headings, bullet points, statistics, no jargon)
