Root cause: SubagentTask had no Media field. Tool results with media
(e.g. image generation) captured result.Media but it was discarded.
AnnounceQueueItem also had no Media field, so PublishInbound for
subagent announces always had empty Media — ContentSuffix never triggered.
Changes:
- Add Media []string to SubagentTask (subagent.go)
- Capture result.Media from tool executions in subagent_exec.go
- Add Media []string to AnnounceQueueItem (announce_queue.go)
- Pass task.Media through direct publish and batched announce drain
- Collect batch media in gateway.go announce queue drain callback
