Resolves WHOOSH-LLM-002: Replace stubbed LLM functions with full Ollama API integration
## New Features
- Full Ollama API integration with automatic endpoint discovery
- LLM-powered task classification using configurable models
- LLM-powered skill requirement analysis
- Graceful fallback to heuristics on LLM failures
- Feature flag support for LLM vs heuristic execution
- Performance optimization with smaller, faster models (llama3.2:latest)
## Implementation Details
- Created OllamaClient with connection pooling and timeout handling
- Structured prompt engineering for consistent JSON responses
- Robust error handling with automatic failover to heuristics
- Comprehensive integration tests validating functionality
- Support for multiple Ollama endpoints with health checking
## Performance & Reliability
- Timeout configuration prevents hanging requests
- Fallback mechanism ensures system reliability
- Uses 3.2B parameter model for balance of speed vs accuracy
- Graceful degradation when LLM services unavailable
## Files Added
- internal/composer/ollama.go: Core Ollama API integration
- internal/composer/llm_test.go: Comprehensive integration tests
## Files Modified
