Added

• added /moogs_structures debug command (on/off/toggle/status) for runtime debug logging, requires permission level 2
• added versioned_single_pool_element — a new jigsaw pool element type that lets datapacks specify different structure templates per Minecraft version range
• added Forge 1.21.2-1.21.3 support

Fixed

• fixed a potential stack overflow crash when two structure sets reference each other via super_exclusion_zone, now detected and skipped per-thread
• fixed piece spawn count cache not clearing on datapack reload, which could cause stale max-count limits to persist across reloads
• fixed structures sometimes always generating the same layout instead of varying
• fixed structures occasionally spawning in or near water/lava when they shouldn't
• improved spawn height accuracy, reducing structures floating or sinking into terrain
• fixed a precision bug that could cause structures to clip into each other or fail to place
• improved structure overlap detection to better prevent intersecting structures
• optimized structure collision checks, improving world generation performance
• fixed a potential crash with unrecognized structure connection types

Changed

• migrated build system from Architectury to Multiloader template
• replaced @ExpectPlatform with ServiceLoader pattern for platform abstraction
