MultiGolem

- Disabled golem healing no longer plays the normal heal feedback when players use matching materials on damaged golems. - Villages can now naturally spawn MultiGolem variants as defenders. - Added server config for village spawn weights. Iron, Copper, Gold, and Emerald are common by default, Diamond is rare, and Netherite has a default weight of `0` so villages do not naturally spawn fire-starting Netherite defenders unless a server owner opts in. - Server owners can now control who may create or heal each MultiGolem tier using Fabric Permissions API-compatible permission providers. - Permissions are permissive by default, so existing servers keep their current creation and healing behavior unless a permissions plugin denies a node. - Permission checks apply to player-built MultiGolem creation, ingot-based healing, marked spawn egg use, and marked spawn egg spawner configuration. - Added Copper, Gold, Emerald, Diamond, and Netherite Golem Spawn Egg variants as marked vanilla iron golem spawn eggs. - The MultiGolem Copper Golem Spawn Egg uses a different icon from the vanilla Copper Golem Spawn Egg, but both spawn eggs have the same name. - Marked MultiGolem spawn eggs can configure monster spawners to spawn the matching MultiGolem variant. - Added a MultiGolem icon and project links for ModMenu and mod list screens.
