Import art/VFX asset packs + game-feel systems; normalize texture extensions to lowercase for LFS

Add BefourStudios SciFi environment packs, Gabriel Aguiar VFX, and the ShaderCrew Toon Shader embedded packages, plus combat/enemy/wave/death gameplay systems and supporting vault docs/screenshots. Rename 11 vendor textures from uppercase .PNG/.HDR to lowercase so the case-sensitive Git LFS filters (*.png/*.hdr) match on case-sensitive filesystems (Linux CI, case-sensitive macOS), not just locally where core.ignorecase=true masks the gap. Each .meta moved with its asset so GUID references are preserved. All ~1000 binaries tracked via LFS. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
