fix: handle broken pipe in query --interactive (#1314)

query_interactive printed the fzf selection with bare print! macros, which panic on EPIPE. Use the pipe_exit convention introduced for broken pipes in #137 like the rest of the command already does.

The final flush makes the error surface deterministically even if stdout buffering would otherwise defer the failed write to process exit.
