test(command): port InitCommandTest

Port the pure-method cases (parse/namespace/formatAuthors/git/vendor-ignore)
and build the ApplicationTester / initTempComposer harness the run cases need.

Supporting production changes:
- carry the streamable input stream as PhpResource (not PhpMixed) and add
  InputInterface::as_streamable so QuestionHelper reads the injected stream
- add StreamOutput/ConsoleOutput __set_stream test helpers and
  ApplicationHandle::set_catch_exceptions for the tester
- implement the interact() author validator via parse_author_string
