- Add internal/templates package for Go template pre-compilation - Implement TemplateEngine with compile-once-render-many pattern - Template caching with LRU eviction policy - Configurable max cache size (default 100) - Compile-time tracking for performance analysis - Per-template render count and latency metrics - Cache statistics: hit ratio, avg render time, total renders - CompileAndRender() for single-call compile+render - Thread-safe concurrent access with RWMutex - 17 template tests, all passing Features: - Compile() caches compiled templates - Render() uses cached templates for fast rendering - GetStats() tracks per-template metrics - GetCacheStats() shows overall cache health - Clear() resets all cached templates - Remove() removes specific template - IsCached() checks if template is pre-compiled Performance: - Template render latency: <100ms ✓ - Caching eliminates parse overhead - LRU eviction when cache full - Concurrent render support - Compile once, render many times Verification: - Render latency < 100ms (verified in tests) - Cache eviction working correctly - Stats tracking accurate - Complex templates supported - Error handling robust Test Coverage: - 17 template tests (compile, render, caching, stats) - Latency verification (< 100ms) - Complex template support - LRU eviction testing - Concurrent access patterns Next: T2.4 (Lessons file indexing)
