"""plugin_system.auto_discover / auto_load_enabled / development_mode.

The General tab offered three toggles for these, with help tips promising
"plugins installed but dormant" and "verbose logging". Nothing in src/,
web_interface/ or scripts/ reads them: every enabled plugin is discovered and
loaded regardless. The toggles are gone; the keys stay tolerated in stored
configs, and saving the General tab must not rewrite them.
