Insta Grow

First release.

Bone meal a sapling, or sneak-place one, and it becomes a full tree instantly — no growth stages, no waiting, no repeated bone meal.

• Works on every vanilla sapling, including the 2x2 mega variants (spruce, jungle, dark oak) and mangrove propagules.
• No tick function. Detection is advancement-driven, so it costs nothing while you play.
• Falls back to a clipped placement when there is no room for the tree, so a sapling in a tight spot still grows without destroying your build. Disable with /scoreboard players set #force insta_grow.config 0.
• Ships two ways from the same payload: a data pack zip for <world>/datapacks/, and a mod jar that works on both Fabric and NeoForge. The jar is an always-on data pack — no Java, no extra dependencies.

Minecraft 1.21.4 through 26.2. Client or server.
