Subject: fix(depends): prefer installed packages over lockfile and add
 platform support

Without --locked, prefer vendor/composer/installed.json over composer.lock
to match Composer's data source priority. Add platform packages (php, ext-*,
lib-*) from detect_platform() so queries like `depends php` work. Show a
specific error message when a platform package is not found.
