fix: coalesce interactive completion backlogs without losing identity

Based on the earliest batching proposal by BrunoBza (#104686) and JoaoMarcos44 structured correction (#104703). Slim redo into topical siblings and shared TUI poller/post-turn routing. Reported by Xipong (#104671). Local shell-to-loopback probes demonstrate 12 to 1 turn dispatches; suites await the campaign test lock.
