[NK2552003]

This pull request prepares the Mac Deep Cleaner project for the v2.0.1 release, introducing APFS clone-aware duplicate detection, updating documentation and metadata, and improving the CI/CD workflow for artifact handling and release automation. The changes span documentation, CI configuration, and project files to ensure consistency and clarity for users and contributors.

Release features and documentation:

• Added APFS clone-aware duplicate detection (opt-in) with sampling profiles, and updated the CLI, documentation, and changelog to reflect these new features and export fields. [1] [2] [3]
• Updated all version numbers and references from 2.0.0 to 2.0.1 in pyproject.toml, src/__init__.py, src/cli.py, docs/ARCHITECTURE.md, docs/COMMAND_REFERENCE.md, docs/PYPI_PUBLISHING.md, and scripts/build.sh. [1] [2] [3] [4] [5] [6] [7] [8]
• Updated the Homebrew formula to point to the new 2.0.1 release tarball.
• Improved documentation links in README.md to use absolute GitHub URLs for all references, and clarified license and documentation sections. [1] [2] [3] [4]

CI/CD workflow improvements:

• Enhanced the GitHub Actions workflow to:
  • Fail early if build artifacts are missing,
  • Download and verify the presence of release artifacts before proceeding,
  • Attach built artifacts to releases automatically, and
  • Add logic to check for the existence of the develop branch before attempting auto-version-bump steps, making the workflow more robust for forks or new repos. [1] [2] [3] [4] [5]

Project organization and planning:

• Updated and reorganized checklist.md and roadmap.md to clarify ongoing and upcoming work, with checklists for optimization, CLI improvements, safety, and mid-term goals. [1] [2]
• Updated the project structure in docs/ARCHITECTURE.md for accuracy and completeness.
