Remaster fifteen original pictures with reproducible artwork cleanup

Add the final boss picture, three coherent terrain remasters and complete DSHP20G3/WORMRITE catalogue families. Preserve generated parents, portable recipes, derivation receipts and separate artistic/context reviews.

Validate 5500 HD pictures with zero rejects and all 45 mods. Review three unchanged 1080p SDL controls, preserve existing runtime/data bindings, and update Linux/Windows shared-data metadata and progress records. Cleanup tools pass 101 tests plus 12 TARGT input-safety tests; TARGT artwork remains pending.
