Vouch v0.3.0-mc1.21.1 (pre-release)

Highlights:

• feat(auth): mixed-mode premium login with cryptographic verification (closes #2 part 1) Replaces the broken v0.2.0 premium auto-login. The mod now intercepts the login handshake and selectively forces an encryption challenge for usernames that exist in the Mojang API, so premium accounts go through the same session-server verification as on online-mode servers. Non-premium players keep the normal offline flow. Default is opt-in: premium_offline_by_default=true makes all players offline by default, players run /vouch markAsOnline to enable premium verification on their next join. Admins can use /vouch admin force-offline <player> and force-online <player> to override per-player.
• fix(build): exclude SLF4J from shadow bundle (closes #2 part 2) HikariCP pulled in org.slf4j transitively and shadow was bundling it. The platform already provides SLF4J at runtime, and the duplicate caused a split-package crash on clean NeoForge installs.

Migration notes:

• The auth.premium_auto_login config option is unchanged but the underlying flow is different. If you were running it on v0.2.0, expect new auth.premium_offline_by_default and auth.premium_auto_login_require_2fa keys in your TOML on first start (defaults are safe).
• New permissions: vouch.admin.premium-override, vouch.command.mark-as-online.
• New DB table vouch_premium_overrides is created automatically on startup.
