Character body and clothing references, and MiniMax H3 memory fixes

[imprsnst]

Summary

• character/encode gains Body and Cloth ports beside the existing face input.
• Each reference stores its role in the manifest next to origin, so old .char files still load.
• Nine H3 slots divide 2:1:1 face/body/cloth by largest remainder, with unused slots redistributed.
• The cap is applied by role inside char_apply, since trimming the tail dropped cloth first.
• verify scores within a role or not at all, and marks body/cloth unscored rather than guessing.
• Body and cloth stay unscored because SFace is face-only and DINOv2 conflates body with clothing.
• Fal-backed nodes now use FalIcon instead of the generic sparkle glyph.
• Minimax H3 memory fixes.
