refactor: switch internal maps/sets from HashMap to IndexMap
Adopt indexmap workspace-wide so iteration order is deterministic and follows insertion order. The non-deterministic order of std HashMap otherwise leaks into resolver decisions when multiple valid solutions exist (e.g. cyclic require pairs under prefer-lowest), making behavior flaky and divergent from Composer's PHP-array semantics.
