Franz Kafka 94322ceff4 feat: Valkey cache for search results ... - Add internal/cache package using go-redis/v9 (Valkey-compatible) - Cache keys are deterministic SHA-256 hashes of search parameters - Cache wraps the Search() method: check cache → miss → execute → store - Gracefully disabled if Valkey is unreachable or unconfigured - Configurable TTL (default 5m), address, password, and DB index - Environment variable overrides: VALKEY_ADDRESS, VALKEY_PASSWORD, VALKEY_DB, VALKEY_CACHE_TTL - Structured JSON logging via slog throughout cache layer - Refactored service.go: extract executeSearch() from Search() for clarity - Update config.example.toml with [cache] section - Add cache package tests (key generation, nop behavior)		2026-03-21 15:43:47 +00:00
