Introduces WhitelistedAuthenticator that wraps an auth.Authenticator to skip
authentication when the client IP matches configured CIDR ranges or exact IPs.
The wrapping happens at service-parse time, transparently covering all handler
types (HTTP, SOCKS4/5, relay, http2, SSH).
Usage:
gost -L 'user:pass@:5999?skipauth=192.168.0.0/24,172.22.22.22/32'
- redisLoader branch used fileLoader instead of redisLoader (copy-paste bug)
- Close() was missing httpLoader.Close() (resource leak vs admission pattern)
- reload() now preserves kvs on load() error instead of wiping to static-only
- load() propagates first loader error, reload() returns early on load failure
- parseAuths scanner errors now logged instead of silently discarded
- http plugin drains body on non-200 to allow keep-alive connection reuse
- Replace manual map-copy loops with maps.Copy
