Add Ollama support for local LLM models (Phase 2 complete)

Browse Source 
Major Changes:
- Added Ollama as alternative LLM provider to OpenAI
- Implemented flexible provider switching via environment variables
- Support for multiple embedding models (OpenAI and Ollama)
- Created comprehensive Ollama setup guide

Configuration Changes (config.py):
- Added LLM_PROVIDER and EMBEDDER_PROVIDER settings
- Added Ollama configuration: base URL, LLM model, embedding model
- Modified get_mem0_config() to dynamically switch providers
- OpenAI API key now optional when using Ollama
- Added validation to ensure required keys based on provider

Supported Configurations:
1. Full OpenAI (default):
   - LLM_PROVIDER=openai
   - EMBEDDER_PROVIDER=openai

2. Full Ollama (local):
   - LLM_PROVIDER=ollama
   - EMBEDDER_PROVIDER=ollama

3. Hybrid configurations:
   - Ollama LLM + OpenAI embeddings
   - OpenAI LLM + Ollama embeddings

Ollama Models Supported:
- LLM: llama3.1:8b, llama3.1:70b, mistral:7b, codellama:7b, phi3:3.8b
- Embeddings: nomic-embed-text, mxbai-embed-large, all-minilm

Documentation:
- Created docs/setup/ollama.mdx - Complete Ollama setup guide
  - Installation methods (host and Docker)
  - Model selection and comparison
  - Docker Compose configuration
  - Performance tuning and GPU acceleration
  - Migration guide from OpenAI
  - Troubleshooting section
- Updated README.md with Ollama features
- Updated .env.example with provider selection
- Marked Phase 2 as complete in roadmap

Environment Variables:
- LLM_PROVIDER: Select LLM provider (openai/ollama)
- EMBEDDER_PROVIDER: Select embedding provider (openai/ollama)
- OLLAMA_BASE_URL: Ollama API endpoint (default: http://localhost:11434)
- OLLAMA_LLM_MODEL: Ollama model for text generation
- OLLAMA_EMBEDDING_MODEL: Ollama model for embeddings
- MEM0_EMBEDDING_DIMS: Must match embedding model dimensions

Breaking Changes:
- None - defaults to OpenAI for backward compatibility

Migration Notes:
- When switching from OpenAI to Ollama embeddings, existing embeddings
  must be cleared due to dimension changes (1536 → 768 for nomic-embed-text)
- Update MEM0_EMBEDDING_DIMS to match chosen embedding model

Benefits:
✅ Cost savings - no API costs with local models
✅ Privacy - all data stays local
✅ Offline capability - works without internet
✅ Model variety - access to many open-source models
✅ Flexibility - easy switching between providers

Version: 1.1.0
Status: Phase 2 Complete - Production Ready with Ollama Support
