 * --include-partial-messages`, which accepts additional user messages while a
 * turn is in flight — the CLI folds them into the current turn as steering
 * (exactly like typing while Claude is working). We bypass the structured
 * `send()` (which would queue the text as a *separate* next turn) and call the
 * raw client's `sendMessage()` so the text lands in the turn already running.
 *
 * Returns true if the message was injected into a live session; false when
 * there is no live client for this root (caller should fall back to queuing).
