fix(launcher): retry activate in post-script loop to beat macOS focus-stealing

All app post-scripts called activate once before the poll loop, then only
checked `frontmost` passively. When Electron retains focus (common when the
app is spawned via run_cmd), macOS focus-stealing prevention blocks the one-
shot activate and VLC/PowerPoint/etc. never come to front. The poll loop
times out and fires the keystroke at Electron instead.

Fix: move activate inside the repeat loop so it re-fires every 0.5s until
macOS yields focus. Also bumped VLC post_delay_ms 1000→2000 and iterations
15→20 for slow conference machines.

Affected profiles: VLC (mac), PowerPoint (mac), LibreOffice (mac+win),
Acrobat (mac+win).
