What is Herdr?
Herdr is an execution environment (a terminal multiplexer) that runs coding agents for multiple projects, each in its own terminal. Terminals stay alive inside a background server, so agents keep working even if you close your laptop or the connection drops, and after a restart it restores the screen layout and sessions. It reads all panes and marks agents as working, blocked, or waiting, and it brings multiple machines together on one screen over SSH. It does not wrap or replace agents; it only handles the terminal.
