feat(loader): wire RootPackageLoader::load end-to-end

Resolve the remaining todo!()/placeholder sites in RootPackageLoader::load
so the root package loads with real data:

- Unbox config at use sites and change load()'s parameter from
  IndexMap<String, Box<PhpMixed>> to IndexMap<String, PhpMixed>, matching
  ArrayLoader::load / VersionGuesser::guess_version and dropping the
  redundant box/unbox round-trip at the factory call site.
- Expose replace_version through CompletePackage/RootPackage inherent
  delegation and a RootPackageHandle method (PHP Package::replaceVersion,
  inherited), and apply it for the auto-versioned default.
- Collect require/require-dev links via getter dispatch and build the
  pretty-string map feeding extractAliases/StabilityFlags/References.

Also reconcile the package repositories type with Config: change
CompletePackageInterface::{get,set}_repositories from
Vec<IndexMap<String, PhpMixed>> to IndexMap<String, PhpMixed> (PHP's
array<int|string, mixed>), wire setRepositories(config.getRepositories()),
and dump repositories verbatim as a keyed array (matching PHP ArrayDumper)
instead of forcing a list.
