fix(remote-filesystem): read scheme-less local paths in get_remote_contents

PHP's getRemoteContents calls file_get_contents unconditionally: the
same stream wrapper reads file:// URLs, plain local paths and network
schemes. The Rust port only handled the explicit "file" scheme, so a
scheme-less local packages.json repository failed with "file could not
be downloaded". Extend the local branch to empty schemes; the http(s)
stub is unchanged.

This clears the first blocker of the create-project functional test;
its ignore reason now documents the remaining ones (live network and
Glob::to_regex emitting PCRE lookaheads the regex crate cannot
compile), which need a user decision.
