[Bug] Draft input discarded when toggling transcript view with Ctrl-O

Bug Description
In Claude Code TUI fullscreen, composing a feedback and pressing Ctrl-O to jump to transcript/wider view (e.g. to copy content from earlier) discards the draft: toggling Ctrl-O back returns an empty input, forcing a full retype. The in-progress input buffer should persist across Ctrl-O transcript-mode toggles rather than being cleared - this is silent data loss of user-typed text. Repro: start typing in the prompt, Ctrl-O, Ctrl-O again -> text is gone.
