v0.6.0

What's New

New Packages

• gokart/fs — Atomic file writes (temp + rename), platform-aware config dir resolution via os.UserConfigDir(), and read-or-create helper
• gokart/kv — Expanded Redis data structure operations (hash, sorted set, set, list, counters) wrapping *redis.Client from the cache package

Web Middleware

• Health checks — HealthHandler and ReadyHandler run dependency checks in parallel with panic recovery, returning ok/degraded/unhealthy statuses
• Rate limiting — Per-IP token bucket rate limiter with configurable RPS/burst and Retry-After headers
• Auth middleware — APIKeyAuth (X-API-Key header or api_key query param) and BearerAuth (Authorization header) with context enrichment callbacks

CLI Scaffolder

• Redis integration — gokart new --redis scaffolds Redis cache wiring; gokart add redis surgically adds it to existing projects
