fix(test-harness): set COMPOSER_TESTS_ARE_RUNNING so interactive tests actually run

Without this, Application::do_run force-disabled interactivity whenever
stdin wasn't a tty (as under cargo test), so ApplicationTester runs with
set_inputs silently produced non-interactive default output instead of
consuming the answers, masking real behavior as several stale #[ignore]s
blaming already-implemented ProcessExecutor/Process todo!()s.

Port composer/tests/bootstrap.php's env setup into a bootstrap() helper
called from get_application_tester(), un-ignore the now-passing
init/update command tests, and update init_command_test's expected
schema-validation wording to match the jsonschema crate (already the
accepted wording per 541a8b4f, not an unported gap).
