two issues:
1. slskd search gave up at 22s (then stopped the search), but slskd gathers peers
over its full ~60s window — so most movie searches were killed before results
arrived. now waits up to 55s but returns early once results SETTLE (12+ hits, or
no new hits for ~12s) so fast searches don't burn the whole window. matches the
music side's longer wait.
2. the automations page re-rendered the WHOLE system section every 8s poll
(replaceChild) → blink + wiped the socket's live progress. now it skips the
rebuild unless something structural changed (added/removed/toggled/ran); live
progress comes via socket, the countdown ticks locally.
