## Why Codex enables enhanced keyboard reporting while the TUI owns the terminal. In iTerm2, exiting the TUI with Ctrl+C can intermittently leave the parent shell receiving raw CSI-u / `modifyOtherKeys` fragments instead of normal key input. Final terminal cleanup should put the parent shell back into normal keyboard reporting even if the terminal misses the usual stack pop. Fixes #19553. ## What Changed - Move TUI keyboard enhancement setup and detection into `tui/src/tui/keyboard_modes.rs`. - Add an exit-only `restore_after_exit()` path that performs the normal keyboard enhancement pop plus unconditional keyboard enhancement and `modifyOtherKeys` resets. - Keep temporary restore paths, such as external-editor handoff, using the balanced stack pop behavior. ## Confidence Medium. This is a speculative fix: I was not able to reproduce the reported iTerm2 behavior manually, but the symptoms line up with terminal keyboard reporting state surviving Codex exit. The added reset sequences are scoped to final TUI shutdown and should be harmless when the terminal is already clean.
