the lists re-read when the agent changes something

an agent deleted two proxy hosts and both stayed on screen. the person had the
answer in the transcript and a stale list six inches above it — which is the
one thing a chat beside a list has to get right, and the reason it is beside
the list at all.

so the chat panel bumps the refresh channel when a turn ran tools, and every
section re-reads. gated on hadToolCalls: a turn that only talked changed
nothing, and re-reading after every sentence would put six requests behind
every reply.

the channel is renamed with it. it was proxy-manager:connection-changed, named
after its only publisher; it has two now and the second is the bigger one, so
it says what it MEANS — something at NPM changed, read it again.
