Run a saved chain from the command line, no window

I run Hangar on one Windows machine beside a local AI agent that already does most of my batch file work from the terminal. Today Hangar.exe has no command-line entry point. Hangar.exe --help opens the window and returns nothing, so anything Hangar does better than my scripts, like HEIC decode, background removal, and the Studios, is out of reach for automation, and in practice I end up not opening Hangar at all. A good outcome looks like: hangar run <chain-name> <file-or-folder> --out <dir>. It runs a saved chain with no window, exits non-zero on failure, and prints a JSON summary of inputs, outputs, bytes, and elapsed time, which is what the runs log already stores. This is a smaller step than the MCP server on your roadmap, and it would make that server thin when it arrives, because both would call the same runner.
