b54e602d - fix: mark message as interrupted locally to prevent loading re-enable

fix: mark message as interrupted locally to prevent loading re-enable When the user clicks stop, the $effect managing $loading relies on isConversationGenerationActive(messages) to detect streaming state. But after invalidateAll() fetches server data, the server may not have written interrupted:true yet (race with the stop POST). The $effect sees streaming=true and only the stopRequested flag prevents $loading from going back to true — but the background poller is never removed (it only stops when streaming=false). Fix: in stopGeneration(), immediately set lastAssistant.interrupted = true on the local messages state. This makes the $effect see streaming=false instantly, which: - Sets $loading = false via the normal path (not just stopRequested) - Removes the background poller (removeBackgroundGeneration) - Prevents any further periodic invalidations from re-enabling loading
