Introduces code.nochebuena.dev/einherjar/cache-valkey — the Valkey cache starter for the Einherjar framework. Absorbs the valkey package from micro-lib and adds three duck-typed adapters that wire directly into auth, web, and auth-jwt. Core: - Provider interface — Get, Set, Del, Exists, Expire, IncrWithTTL, Native() - Component interface — lifecycle.Component + observability.Checkable + Provider - Config struct (EINHERJAR_VALKEY_* env vars) - New(logger, cfg) Component — creates valkey-go client in OnInit; PING in OnStart; logs "valkey: connected" - IncrWithTTL implemented with Lua script (atomic INCR + conditional EXPIRE); race-free fixed-window semantics with no MULTI/EXEC overhead - Priority: LevelDegraded — Valkey outage degrades, does not halt the service Adapters (duck-typed — no import of auth, web, or auth-jwt): - PermissionCache — Get/Set int64 bitmasks as string; satisfies auth/rbac.Cache - RateLimiterStore — fixed-window via IncrWithTTL; satisfies web/mw.RateLimiterStore - Blacklist — Exists/Set "1" with TTL; satisfies auth-jwt.Blacklist Compliance test verifies CT-6, duck-type shape assignments, and full adapter behavioural coverage with a mockProvider (no live server required). - Component interface embeds observability.Identifiable; identifiable.go implements ModulePath and ModuleVersion via runtime/debug.ReadBuildInfo() — prints in launcher banner
