miden-package-registry

Shared package registry interfaces, metadata types, and dependency resolution for Miden packages.

This crate provides:

• PackageRegistry, the read-oriented trait used by package resolution and project dependency graph construction
• PackageResolver, a PubGrub-backed resolver generic over any PackageRegistry
• InMemoryPackageRegistry, a simple BTreeMap-backed implementation for tests and embedding
• shared metadata types such as PackageId, Version, VersionRequirement, and PackageRecord

Version resolution currently follows these rules:

• each package semantic version maps to at most one canonical published artifact in the registry
• semantic version requirements select the latest available matching canonical semantic version
• digest requirements match only the exact package digest
• exact semver#digest requirements match only that canonical published artifact
• indexed package dependencies are stored as exact resolved requirements from published artifacts

Artifact storage is intentionally out of scope for this crate. Concrete registries are expected to pair the metadata/index implementation here with their own package storage strategy.
