fix(locker): return stability-flags as int, not string

Locker::get_stability_flags returned IndexMap<String, String>, converting
each value via PhpMixed::as_string(), which only matches the String
variant. composer.lock's "stability-flags" values are always JSON
integers (BasePackage::STABILITIES), so every flag silently decoded to
"" and installer.rs's downstream .parse::<i64>() defaulted it to 0
(stable). This made any locked package pinned via a non-stable
stability-flags entry look "unacceptable" during `composer install`,
silently dropping it from the solver's pool instead of fixing/requiring
it — turning a real dependency conflict into a spurious "lock file needs
changes" result. Return i64 directly, matching
RootPackageInterface::get_stability_flags and set_lock_data's existing
convention for this same PHP array shape.
