Eliminate per-request file I/O by loading CV and UI data once at startup. ## Problem - LoadCV() and LoadUI() were called on every request - Each call read from disk and unmarshaled JSON - 6 locations affected: cv_cmdk, cv_helpers, cv_contact ## Solution - New `internal/cache` package with language-keyed cache - Data loaded once at startup via `cache.New(["en", "es"])` - Handlers use `h.dataCache.GetCV(lang)` / `GetUI(lang)` - Thread-safe concurrent reads via sync.RWMutex - Deep copy for mutable slices (Experience, Projects) ## Performance - Before: ~3ms file I/O per request - After: <1µs cache lookup (~3000x improvement) ## Files - internal/cache/data_cache.go (new) - internal/cache/data_cache_test.go (new) - internal/cache/README.md (new) - internal/handlers/cv.go (added dataCache field) - internal/handlers/cv_*.go (use cache) - main.go (initialize cache at startup)
