- Ensured correct `Content-Type` header for catalog artifacts (`catalog.attrs` and `catalog.*`) in HTTP responses.
- Added SHA-1 based weak ETag generation for manifest responses to improve caching and legacy compatibility.
- Updated `integration_tests` to validate content-type and ETag correctness.
- Added new dependency `sha1` for hashing support.
- Expanded repository structure by introducing methods for fetching legacy catalogs, catalog file paths, and repository info.
- Added new REST API v1 endpoints for catalog, manifest, file, and publisher handling.
- Implemented `publisher` handler module with `get_publisher_v0` and `get_publisher_v1` methods to retrieve publisher details in pkg5 format.
- Updated `integration_tests` to validate new endpoints and ensure compatibility with legacy and modern catalog/manifest handling.
- Removed unused dependency `walkdir` and refactored test cases for clarity and efficiency.
- Implemented `DepotRepo` for repository access, including methods for catalog path, file path, and manifest retrieval.
- Introduced foundational HTTP routes for catalog, manifest, file, and package info retrieval.
- Added integration tests to validate repository setup and basic server functionality.
- Modularized HTTP handlers for better maintainability and extended them with new implementations like `info` and `manifest` handling.
- Refactored `main` function to simplify initialization and leverage reusable `run` logic in a new `lib.rs`.
- Updated `Cargo.toml` and `Cargo.lock` to include new dependencies: `walkdir` and updated testing utilities.
- Added initial implementation of the `pkg6depotd` server with modular components for CLI parsing, configuration management, HTTP handling, repository access, and daemonization.
- Implemented basic server startup logic with a default router and placeholder handlers.
- Integrated telemetry initialization and configuration fallback mechanism for ease of development.
- Updated `Cargo.toml` and `Cargo.lock` to include dependencies necessary for server functionality.
- Add methods to find and clean up obsoleted packages older than a specified TTL (`find_obsoleted_packages_older_than_ttl` and `cleanup_obsoleted_packages_older_than_ttl`) in `libips`.
- Implement a new `CleanupObsoleted` command in `pkg6repo` to handle cleanup operations.
- Update workspace `Cargo.toml` files with unified attributes for better consistency.
- Adjust dependencies (`libips` version patterns, `thiserror` updates) and enhance metadata management for obsoleted packages.
- Enhance repository operations by adding batch processing and robust logging during cleanup.
