Free Hosting Kills Bots Without HTTP Ports—Here's the One-Line Fix

Bots on free hosting often go offline because platforms health-check via HTTP, but bots don't listen on a port. The fix is to run a tiny HTTP server alongside the bot, like StayPresent, which starts a web server and launches the bot as a subprocess. This one-line solution prevents the platform from marking the bot as unhealthy or restarting it.
