RetroAPI

StationAPI mods now get the same automatic treatment RetroAPI mods do.

Creative tabs

• Auto tabs now include mods that register through StationAPI, not just RetroAPI. A mod that has never heard of RetroAPI gets a tab named after itself.
• Spawn eggs are no longer duplicated into the owning mod's tab, since they already sit in the Spawn Eggs tab. Eggs from other mods are left where they are.

Spawn eggs

• Automatic eggs now work under StationAPI. The sweep reads vanilla's EntityRegistry, which both toolchains populate. Living entities only.
• The fallback egg is tinted from a saturation weighted average of the mob's own render texture, so eggs are distinguishable before anyone draws one. Drop a sprite at assets/<mod>/textures/item/<mob>_spawn_egg.png to replace it.

Opting out without a dependency

• com.periut.retroapi.compat.RetroOptional takes only Strings, so a mod can call excludeItemGroup, excludeSpawnEggs and excludeSpawnEgg reflectively with no hard dependency on RetroAPI.
• templates/RetroCompat.java.txt is a copy in helper that wraps the mod check and the reflection, and does nothing when RetroAPI is absent.

Fixes

• The handshake length widener uses ModifyArg instead of ModifyConstant. Only one injector may claim a constant, so RetroTweaks and Glass Networking previously fought over it and whichever lost crashed on startup. Both now apply.
