Replaces the misc/build.func bootstrap with the two-root core loader.
No other change: the engine contract (var_*, update_script, start,
build_container, description) is identical on both engines.
The update script wiped public/uploads and did not re-apply www-data
ownership, causing HTTP 500 after successful updates. Align with upstream
upgrade steps and sibling Laravel scripts by backing up uploads/dist,
restarting PHP-FPM, running full artisan cache cycle, and adding verbose
diagnostics.
