/**
 * What phren knows about a coding agent running on this machine.
 *
 * phren does not spawn or supervise these; it discovers them from whatever is
 * already managing them — a Herdr workspace, phren-agent's own multi-agent
 * spawner, a tmux session — and joins them onto the knowledge graph by the
 * directory they are working in.
 *
 * The contract is deliberately small and host-agnostic. Anything that can
 * print this shape is a provider, which is why a tmux or Zellij user needs a
 * few lines of shell rather than a change to phren.
