- Deleted `pkg6dev` crate, including all related files (`src`, `Cargo.toml`, `Cargo.lock`, and `README.md`).
- Removed error handling, CLI logic, and publishing functionality from the project.
- Migrated relevant high-level APIs to `libips`, ensuring consistency with existing modules.
- Updated `libips` with a new `api` module to encapsulate `forge/pkgdev` integration logic.
- Simplified repository structure to exclude now-unused components and dependencies.
- Added `pkgtree` with functionalities to analyze dependency trees and detect cycles in IPS package images.
- Implemented CLI options for filtering by publisher, package substring, and output format (Tree/JSON).
- Integrated cycle detection and suggestions for resolving dependency cycles.
- Added testing support for cycle detection.
- Updated workspace dependencies and added `pkgtree` to the workspace configuration.
- Implement unit tests to cover `Image` creation, metadata management, saving/loading, and error handling.
- Add separate constructors for `Full` and `Partial` image types (`new_full`, `new_partial`).
- Introduce robust path handling methods (`metadata_dir`, `image_json_path`) for consistent metadata structure.
- Enhance error diagnostics with `InvalidPath` variant in `ImageError`.
- Update `Cargo.toml` for test module inclusion.
- Centralize package metadata in workspace for consistency.
- Upgrade `pkg6dev` and `pkg6repo` to version `0.5.1`, aligning with new workspace configuration.
- Introduce `EnvFilter` for dynamic logging configuration, defaulting to debug level.
- Add `LoggingEnvError` variant to `Pkg6DevError` with structured diagnostics for improved error handling.
