/**
 * Live coding agents on the knowledge graph.

 * Watch mode shows what phren's memory is doing; this shows who is doing it.
 * Agents are transient runtime state rather than memory, so they decorate the
 * project nodes they are working in instead of becoming graph nodes of their
 * own — the same shape `GraphWatch` uses, and it keeps `graph-core` (which is
 * bundled for the browser) untouched.
