… its source recv.subagent-spawned was emitted only by the local IPC handler, so remote and local-transcript subagents never appeared in the trace even while their running dot was painted. noteSubagentActivity now emits it with the source (local-ipc, remote-watch, local-transcript); recv.subagent-completed carries via ipc / ttl / parent-cleared. Closes #291.
