Summary of Changes

Hello @elrrrrrrr, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a critical issue preventing package installations when distribution tags are used, while simultaneously boosting the performance of package version resolution. It achieves this by introducing a structured approach to handling version information, optimizing caching mechanisms, and ensuring the new logic is thoroughly tested.

Highlights

• Dist-tag Resolution: Implemented robust resolution of package versions by prioritizing distribution tags (e.g., "latest", "beta") before falling back to semantic versioning (semver) matching. This change directly addresses and fixes installation failures that occurred when using tags.
• VersionsInfo Structure Refactoring: The VersionsInfo struct has been refactored to explicitly store version_list and dist_tags as structured data, moving away from a generic serde_json::Value. This improves type safety, clarity, and maintainability of package version data.
• Caching Optimization: Optimized the loading performance of versions.json by introducing a new memory cache layer for full manifests. This enhancement reduces redundant disk I/O operations when resolving individual version manifests, leading to faster package resolution.
• Enhanced Test Coverage: Comprehensive unit tests have been added for the new dist-tag resolution logic, covering various scenarios including direct tag matches, semver fallbacks, edge cases with empty tags, and error conditions, ensuring the reliability of the new implementation.

Code Review

This pull request introduces a fix for package installation with dist-tags and optimizes versions.json loading. The changes to use strongly-typed VersionsInfo and Versions structs are a great improvement for type safety and clarity. The new caching logic in resolve_version_manifest and the dist-tags handling in resolve_package are well-implemented.

However, I've found a critical issue in the caching logic of resolve_package_versions that needs to be addressed. Additionally, there are a couple of test removals that reduce test coverage for important edge cases, and a use of unwrap() that should be replaced for better robustness.
