Ports four nodes from the EmpireTitan pack into the Badman naming
convention: Color Match (with preset save/load + live preview), Color
Match Combine Presets, Chroma Clean matte refinement, and a tiled
BiRefNet/RMBG wrapper that recovers fine-edge detail. Updates README,
bumps version to 1.3.0, adds .gitignore, and fixes a stale display-name
key for IO Config.
