Add a new "utls" dialer type that uses the refraction-networking/utls library to mimic browser TLS fingerprints (Chrome, Firefox, Safari, etc.). - x/dialer/utls/dialer.go: Registered as "utls", mirrors the TLS dialer with Handshake() using utls.UClient() for fingerprint emulation. - x/dialer/utls/fingerprint.go: Maps string names (chrome, firefox, ios, safari, edge, randomized, golang, custom) to utls.ClientHelloID presets. - x/dialer/utls/metadata.go: Parses fingerprint from dialer metadata. - go.mod: Add github.com/refraction-networking/utls v1.8.2. The fingerprint is dialer-only metadata — the standard TLS dialer is untouched. Falls back to crypto/tls if no fingerprint is configured. Closes go-gost/gost#31
