A new remote flag, on by default, controls message-input split repair

A new remote flag, on by default, reassembles split message-tool inputs when they are read back.

What

tengu_deep_feather is new and its fallback is true, so absent a server value it is on for everyone. It governs whether split message-tool inputs are reassembled, both when the tool reads its own input and when a prior tool call is re-read to recover its original message and idle-subscription values.

Details
  • Effectively a kill switch: if remote config turns it off, previously split inputs stop being reassembled on the round trip.
  • Notable as the only new flag here that defaults on rather than off.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
