Hatchable

Renamed Egg Hatcher to Hatchable and changed its namespace to hatchable. Existing recognized settings migrate automatically.

Added composable Hatch Mappings:

• Optional items, hatchers and predicate selectors control what and where items can hatch.
• hatchers checks block IDs or tags directly underneath the dropped item; omitting it allows the rule to hatch anywhere.
• Rules can spawn any entity, merge custom entity data, inherit compatible item components, and override chance, age and density settings.
• Later matching values take priority, while entity_data compounds merge.

Added default support for temperate, cold and warm chicken variants, with organized egg and variant tags.

Rebuilt the config interface with global Force options, editable mappings, configurable hatch feedback, and categorized debug controls.

Expanded compatibility to Minecraft 1.21 through 26.3.
