v3.0.6

The run's root reads its whole root-stream.jsonl before its output parts (on Discovery run magnetar-rust-sandbox-20261031b the parts held 150 of the root's 302 tool calls for the same turn). Includes 3.0.5: a journal that never spawns its root still records it, and a settled node with no other conversation keeps its recorded live stream and execution-total usage. Adapter 2.7.3. See #393 and #391.
