The autoloader that got slower after a directory was added

A new PSR-4 root added to composer.json, and an authoritative classmap that had to be regenerated and was not.

# added
"autoload": { "psr-4": { "App\": "src/", "Tools\": "tools/" } }

# the deploy ran dump-autoload --classmap-authoritative
# BEFORE the tools directory existed in the image,
# because .dockerignore excluded it.

# result: every Tools class missing from the map, and
# authoritative means a miss is fatal rather than a
# fallback to PSR-4 resolution.

An authoritative classmap turns a missing entry into a class-not-found error rather than a slow lookup, which is the right trade and makes the build order matter. The failure appeared only on the one console command that used the new namespace, which is why it reached production — and the check is asserting the class count in the generated map.
