Loading xdebug.mode=debug at all times made every drush/composer command
noticeably slower, since Xdebug hooks every function call as soon as the
mode is active regardless of whether a debugger connects. Split the config
per-SAPI instead: CLI defaults to xdebug.mode=off (opt in with the new
xdebugon/xdebugoff aliases or XDEBUG_MODE=debug XDEBUG_TRIGGER=1), while
php-fpm keeps xdebug.mode=debug + start_with_request=yes so browser
requests still auto-connect with no trigger needed.
