Michael Zeng 341de32c33 Allow root turn suspension with live descendants (#54414)
## Why

Live descendants previously blocked suspension of an unfinished root turn, requiring callers to stop and unload them before recovering the root elsewhere.

## What changed

Allow `suspend_turn_and_shutdown` to suspend the root and initiate shutdown of all sessions sharing its local agent runtime, fencing new starts. Remove `SuspendTurnOutcome::HasLiveDescendants`.

Success confirms that the root has stopped and its history writer is flushed and closed; descendant cleanup completes separately. Callers must finish tree shutdown or fence and terminate the tree's persistence writers before transferring ownership. Interrupted descendants are not automatically recovered.

## Testing

Extend integration coverage to verify child shutdown, recovery under the original root turn ID without restarting children, and separate reporting of child writer failures.

codex-protocol

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.

This crate should have minimal dependencies.

Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
