HeadSmith

Custom Head Overrides

- Added override: true option for custom head definitions to replace bundled heads with the same ID - Without the override flag, duplicate head IDs still error to prevent accidental conflicts - Plugin now logs a summary of replaced heads when custom overrides are applied - Updated README with documentation on custom heads and override usage

Silk Touch Drop Rules

- Mini blocks made from valuable materials (diamond, emerald, gold, netherite) now have conditional drop rules - Without Silk Touch: Drops the vanilla block material - With Silk Touch: Drops the mini block head - This applies to both base mini blocks and alphabet blocks derived from these materials (but not to other heads, like gold chalices) - Added valuable_drop_materials configuration in generate_config.toml - Updated generation scripts to support drop sections for valuable materials
