Add comprehensive scoring system with three strategies: - RelevanceScorer: Semantic similarity with keyword fallback - RecencyScorer: Exponential decay with type-specific half-lives - PriorityScorer: Priority-based scoring with type bonuses Implement CompositeScorer combining all strategies with configurable weights (default: 50% relevance, 30% recency, 20% priority). Add ContextRanker for budget-aware context selection with: - Greedy selection algorithm respecting token budgets - CRITICAL priority contexts always included - Diversity reranking to prevent source dominance - Comprehensive selection statistics 68 tests covering all scoring and ranking functionality.

Context Management Engine
|
|
|
|
Sophisticated context assembly and optimization for LLM requests.
|
|
Provides intelligent context selection, token budget management,
|
|
and model-specific formatting.
