feat: Enhanced Context Condensation - 8 methods with analytics 

- Optimized existing condensation methods (hierarchical, conversational, semantic, algorithmic)
- Added 4 new condensation methods (sliding_window, importance_based, entity_aware, code_aware)
- Fixed critical bugs in conversational and semantic methods (undefined variables)
- Added internal model warm-up functionality for faster first inference
- Implemented condensation analytics (effectiveness %, latency tracking)
- Added similarity detection in algorithmic method using difflib
- Support for condensation method chaining

- Automatic cache initialization on startup
- Skip caching for streaming requests
- Comprehensive test suite with 6 test scenarios
- **Enhanced Context Condensation**: 8 condensation methods for intelligent token reduction
- Hierarchical: Separates context into persistent, middle (summarized), and active sections
- Conversational: Summarizes old messages using LLM or internal model
- Semantic: Prunes irrelevant context based on current query
- Algorithmic: Removes duplicates and similar messages using difflib similarity detection
- Sliding Window: Keeps recent messages with overlapping context from older parts
- Importance-Based: Scores messages by importance (role, length, questions, recency)
- Entity-Aware: Preserves messages mentioning key entities (capitalized words, numbers, emails)
- Code-Aware: Preserves messages containing code blocks
- Internal model improvements with warm-up functionality
