feat(autoload): generate Composer-compatible PHP autoloader files

Implement autoloader generation that produces all standard Composer
autoloader files (autoload.php, autoload_real.php, autoload_static.php,
autoload_psr4.php, autoload_namespaces.php, autoload_classmap.php,
autoload_files.php, installed.php) plus embeds ClassLoader.php,
InstalledVersions.php, and LICENSE from the Composer submodule. Wire
into the install command (gated by --no-autoloader) and replace the
todo!() in dump-autoload with a working implementation.
