Subject: [PATCH] fix: include must-use plugins and drop-ins in SITE.md
 scaffold

SITE.md only queried get_option('active_plugins'), missing mu-plugins
and drop-ins entirely. Add ## Must-Use Plugins section via get_mu_plugins()
and ## Drop-ins section via get_dropins(), both with the same name +
truncated-description format used by Active Plugins.

Closes #1055
