- Add methods to dump and analyze table contents in `InstalledPackages` and `ImageCatalog`.
- Introduced `Image::refresh_catalogs` to support refreshing catalogs selectively or fully for specified publishers.
- Enhanced `CatalogManager::load` to handle missing fields gracefully, including fallback mechanisms for `packages`.
- Added detailed logging and error diagnostics for catalog parsing and directory operations.
- Improved publisher-specific directory management, including cleaning and recreating directories during full refresh.
- Updated tests to verify correct behavior for catalog directory clearing and new catalog handling logic.
- Introduced the `ImageType` enum to support both `Full` and `Partial` image types during creation.
- Updated `Image::create_image` to accept `ImageType` as a parameter.
- Enhanced logging with detailed debug statements for catalog building, image queries, and package processing.
- Refactored CLI to include a new `--type` option for specifying image type during image creation.
- Simplified path determination logic in `pkg6` with a new `determine_image_path` helper function.
- Removed unused imports and unnecessary file checks for cleaner code.
- Introduced `ImageCatalog` for handling catalog-related operations, including initialization, building from publishers, querying, and manifest management.
- Added `InstalledPackages` for managing installed package operations, such as adding, removing, querying, and retrieving manifests.
- Defined database schemas and error types to support both modules.
- Refactored table handling, ensuring consistent transaction scoping with `redb`.
- Add `ProgressReporter` trait with `start`, `update`, and `finish` methods for customizable progress tracking during operations.
- Implement `ProgressInfo` struct for detailed progress state reporting, including operation, progress, and context information.
- Create a no-op implementation `NoopProgressReporter` for cases where progress reporting is not needed.
- Enhance `pkg6` with structured error handling using `Pkg6Error` and new diagnostic variants for I/O, JSON, FMRI, and logging errors.
- Update `Image` functionality to leverage progress reporting during catalog downloads and include robust publisher management.
- Introduce `TestProgressReporter` for unit tests to validate progress reporting integration.
