Behavior proof:

• Before: native Codex command/tool items present only in the final turn/completed snapshot were recorded in transcript state but did not emit normalized item/tool progress events for channel verbose surfaces.
• After: terminal snapshot-only native tool items synthesize item/tool start/result progress, while already-started items avoid duplicate starts, running snapshots do not fake completion, and prior-turn snapshot replays with item turn ownership are ignored.
• Not tested live: Telegram roundtrip against the reported install.
