fix(launcher): replace fixed post_delay with frontmost poll across all launch profiles

`open -a App` returns immediately; a fixed delay is unreliable for cold starts.
Each post_script now polls every 500 ms (up to 7.5 s) until the target process is
frontmost before firing the automation keystroke. Keynote polls document count
instead of frontmost since start(front document) requires the file to be loaded.
Mac profiles: post_delay_ms 2000 → 1000. Win/Parallels profiles: 3000 → 1500.
