Subject: [PATCH] fix(serve): continue past transient accept errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously a single EMFILE / EINTR on listener.accept() returned from
run_accept_loop entirely, killing the host's HTTP viewer fanout for the
rest of the session. Most accept errors are transient — log and loop.
