A delegated message was delivered into the worker's input box but never
submitted, so no task was ever processed: bridge_send blocked until timeout
while the worker sat idle with the prompt typed but not entered.
herdr's agent.send delivers text as a bracketed paste; a trailing carriage
return in that same call is swallowed as literal newline content, not Enter.
AgentControl.send now emits two keystroke events — the payload, then a
standalone "\r" — so the worker actually submits and runs the task.
Verified live (Claude Code v2.1.210, off-sub worker): full hands-off
bridge_send -> auto-submit -> worker computes -> bridge_reply round trip
returns the reply in ~41s. 62 tests green.
