A pi extension that adds fully async, interactive subagents running in Herdr panes.
subagent() returns immediately — the sub-agent runs in its own terminal pane that never steals keyboard focus, while a live widget above your input tracks every running sub-agent. When one finishes, its result is steered back into the main session as a notification that triggers a new turn. Spawn several in parallel and keep working; each result arrives independently as it completes.
Built in TypeScript as a pi extension, installable via pi install npm:pi-interactive-subagents-herdr.
