Cli Anything Blender

This gives Claude a stateful CLI for driving Blender through JSON scene descriptions and bpy script generation. It's built on the same patterns as the GIMP CLI harness, so you get undo/redo, REPL mode, and dual output formats for both humans and agents. The real win is the preview system: you can capture actual Eevee or Workbench renders into bundles with hero.png artifacts, and run live preview sessions that track a command-to-visual trajectory. Useful when you need Claude to iterate on 3D scenes with truthful visual checkpoints instead of guessing what the JSON will look like. Just remember agents must use absolute paths for rendering and project files, and always pass the --json flag for parseable output.
