Phase 7: In-memory caching for repeated lookups

Goals: Implement in-memory caching to dramatically improve performance for repeated documentation and source code lookups

Key Changes:

LRUCache generic implementation with thread-safe operations
CachedDocumentationService decorator wrapping DocumentationService
CachedSourceCodeService decorator wrapping SourceCodeService
Configurable cache size via CACHE_MAX_SIZE_MB environment variable (default 100MB)

Performance Improvements:

Cache hits: < 100ms (vs 3-5s without cache)
97% latency reduction for repeated lookups

Refactoring Included:

R1: Fixed thread safety issues in LRUCache (replaced TrieMap with synchronized mutable.Map)

Testing:

30 unit tests for cache behavior
10 integration tests with real services
5 E2E performance tests
