| * E2E test for the Ctrl+F model toggle hotkey. | ||

| * a non-kitty PTY would send for Ctrl+F — and asserts the "Switched | ||
| * to" message appears in the TUI output. | ||

| * NOTE: PTY-based interactive tests don't work on Windows (node-pty | ||
| * limitation). Skipped via IS_WINDOWS guard. | ||

[Suggestion] E2E test never terminates the PTY process
runInteractive()returns{ ptyProcess, promise }but onlyptyProcessis destructured. The CLI process is never stopped —rig.cleanup()only deletes the test directory. Orphaned PTY processes accumulate during test runs.Then at the end of the test, gracefully exit:
