Command output that arrives during a running turn is now held until the turn ends

What

A turn is one round of Claude working on your request. Before this release, messages produced by commands during a running turn were inserted into the conversation straight away, in the middle of the turn. A new appendAfterTurn path now holds them back:

• It covers failed immediate commands sent over the bridge (remote control), where the failure row reads "failed (detail withheld on this connection)", meta messages from commands, a helper that appends meta rows, and several slash-command and printRows call sites.
• While a turn is running, these rows wait in _rowsHeldForTurnEnd. When the turn stops, _releaseRowsHeldForTurnEnd adds them to the conversation, as long as it is still the same turn that was running.
• The behaviour sits behind the server-side flag tengu_foamy_spring, which counts as on when the server gives no value. When the flag is off, rows are added immediately, as before.

Why

Output from a command you run while Claude is responding now appears after the response instead of interleaving with it. That keeps the turn's messages in order and avoids a streaming reply being broken up by unrelated rows.
