waaseyaa/cache#

Layer 0 — Foundation

Cache abstraction for Waaseyaa applications.

Provides a backend-agnostic CacheInterface with a MemoryBackend for tests and a filesystem backend for production. Supports atomic file writes (write-to-temp-then-rename) to prevent partial reads. Also includes CacheConfigResolver for cache-control header computation.

Key classes: CacheInterface, MemoryBackend, FilesystemBackend, CacheConfigResolver.
