refactor(autoload): drop the todo!() composerRequire stub

The real port lives in shirabe-php-rpc as __shirabe_composer_require(),
which runs inside the PHP worker where $GLOBALS and `require` exist.
Record that pointer in the module doc instead of keeping a stub that
can never be implemented on the Rust side.
