feat(phase-c): resolve reflection/downcast phase-b TODOs

Resolve category F phase-b TODOs (class-string, instanceof, get_class,
method_exists, __FILE__, Reflection API, downcast).

- VcsRepository: dispatch drivers through a VcsDriverKind enum
  (instantiate/supports/php_class_name) and add constructors to the
  concrete VCS drivers
- repository downcasts via RepositoryInterfaceHandle::downcast_rc and
  as_any (init/show commands, vcs ValidatingArrayLoader)
- BaseCommand::is_self_update_command override replaces an instanceof
- Factory::create narrows PartialComposer to ComposerHandle via as_full
- InstalledVersions gains set_self_dir/set_installed_is_local_dir,
  replacing Reflection-based static property mutation
- ClassLoader::as_array_iter ports the PHP (array) cast
- drop the unnecessary __FILE__ phar branch in self-update

application get_class(command) reclassified TODO(plugin); buffer_io
StreamableInputInterface downcast and the ValidatingArrayLoader trait
redesign left as tracked TODOs.
