The other half of making a spawned agent visible. The commander's pane now lists
its children; opening one gave no way back — no link to the conversation that owns
it, and nothing to tell it apart from a chat somebody had started themselves and
forgotten.
`parentCommanderOf` is the row `ingestSpawnedChildren` already writes, read from
the other end. So this needed no table and no write path: a commander's children
were recorded because deleting one has to take them with it, and that record
answers "who is my parent" for free. Nothing had asked.
`GET /chat/sessions/:id` carries `spawnedBy`, and the chat panel renders one line
above the transcript linking back to the commander. Null for almost every session,
which is the normal case rather than a miss — a chat somebody opened has no parent
— so the bar renders nothing at all rather than saying so. Never fatal: a session
must open when this lookup will not.
