- Updated `FileBackend::open` calls to use immutable `repo` variables across multiple modules.
- Improved dependency action string construction by integrating optional properties, predicates, and facets for better clarity and flexibility.
- Transitioned the catalog backend from `redb` to `rusqlite` for better compatibility and concurrency.
- Updated `IpsProvider` to use SQLite for package querying, dependency resolution, and obsolescence handling.
- Removed `decode_manifest_bytes_local` and unused `manifest` cache logic.
- Simplified catalog-related functions and integrated `sqlite_catalog` module.
- Enhanced test functions and added schemas for managing SQLite databases.
- Introduced a searchable index with structured `IndexEntry` support for packages, files, directories, and dependencies.
- Added `search` method in `DepotRepo` with wildcard and case-sensitive query handling.
- Created `/search/0` and `/search/1` routes for search API, supporting publishers and token-based queries.
- Updated `SearchIndex` handling to map tokens to detailed `IndexEntry` structures.
- Improved index building to include attributes for files, directories, and dependencies.
- Adjusted indentation and line breaks for structs, functions, and method calls to comply with Rust formatting standards.
- Improved error message formatting and consistency across `PkgTreeError` instances.
- Restructured long function arguments and chained calls for clarity and maintainability.
- Simplified conditional statements and loops for better readability.
- No functional changes introduced.
- Introduced caching headers (`Cache-Control`, `ETag`, `Last-Modified`) for file responses to improve client-side caching.
- Added HTTP admin routes for health check and authentication validation.
- Made `cache_max_age` configurable via server configuration with a default of 3600 seconds.
- Enhanced file handler with metadata-based `Last-Modified` computation.
- Updated integration tests to cover new functionality and ensure correctness.
- Removed now-redundant catalog path resolution logic in `repo.rs`.
- Updated `file_backend` with a unified method for fetching catalog file paths, addressing invalid path prefixes.
- Adjusted HTTP handler to use the updated method.
- 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.
