Litematica command on forge

## What do you need help with?
Is there an equivalent for the litematica command for recent forge version? Litematica is fabric only, and schematica has not been updated for a while. What is possible on forge 1.19 or 1.20 ?
Is forgematica compatible? Other schematics viewers ?

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any OwO's or UwU's in this issue.

Start by reviewing the request and the repository's current Forge and Minecraft version support. Determine whether Forge 1.19 or 1.20 support, Forgematica compatibility, or another schematic viewer is feasible; done would require a clear, documented answer or a defined implementation scope.
