fix: Add startup.sh script for automatic native module rebuilding

- Prevents Node module version mismatch crashes in production
- Automatically rebuilds native modules on every restart
- Ensures dependencies and build exist before starting
- Increases max_restarts to 50 to handle transient issues
- Reduces min_uptime to 10s for faster recovery
- Increases memory limit to 256M for stability

This fixes the 'errored' state after 10 restarts issue and ensures
the service stays up even after Node version changes on the server.
