Subject: refactor(package): rename traits and switch dep maps to IndexMap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename Package/CompletePackage to PackageInterface/CompletePackageInterface
to mirror Composer's interface names, and split each into its own module
under crates/mozart-core/src/package/.

Switch dependency-link and metadata maps from BTreeMap to indexmap::IndexMap
so serialized JSON preserves the original key ordering rather than sorting
alphabetically — matching PHP associative-array semantics. The
--sort-packages behaviour in `require` is preserved via sort_unstable_keys.
