Concurrent agent searches queue into a search-results column — fire many, deal with them as they come

Agent searches take minutes, and today each one hijacks a single column the operator must babysit. Wanted: a search-results microfrontend on the far right — every fired search appends a collapsed card with status, progress, and expected wait; a signal fires when results land; expand to act, mark complete to clear. Run several at once, triage on arrival.
