Andrew Kaszubski ae7899a6fc feat(dataflows): add data caching layer with rate limit awareness - Fixes #12 
Implements [DATA-11] Data caching layer - FRED rate limits with:
- CacheEntry: Generic cache entries with TTL and metadata
- CacheStats: Hit/miss/stale statistics tracking
- RateLimitState: Per-source rate limit tracking with exponential backoff
- MemoryCache: In-memory LRU cache backend
- FileCache: File-based JSON cache backend
- DataCache: Main cache with source-specific TTLs and stale-while-rate-limited
- @cached decorator: Function result caching

Features:
- Multi-backend support (memory, file)
- TTL-based expiration with configurable per-source defaults
- Stale-while-revalidate when rate limited
- Thread-safe operations throughout
- 41 tests covering all components
