feat(shirabe): resolve phase-b TODOs with shared ownership

Replace TODO(phase-b) placeholders (todo!() and commented-out code)
with real implementations:

- Share JsonFile via Rc<RefCell<JsonFile>> so JsonConfigSource and the
  owning command can hold the same instance (base_config_command,
  config_command, repository_command, require_command, create_project,
  remove_command, factory)
- Change InstallerInterface methods (is_installed, download, prepare,
  cleanup, get_install_path) to &mut self so initialize_vendor_dir can
  run, propagated to all installer implementations
- Pass io/config/filesystem/process by clone instead of moving or
  stubbing (auth_helper, svn_driver, curl_downloader, library_installer)
- Make TransportException Clone and store it by value in VcsRepository
- Clone operations in Transaction sort, root_aliases/temporary_constraints
  in RepositorySet::create_pool, and share CompletePackage via handle in
  PlatformRepository
- Wire up set_option, set_requires/set_dev_requires, installation manager
  setters, BumpCommand::set_composer, and clean_backups/set_local_phar
