SlimStack v0.2.0

SlimStack v0.2.0

Bug Fixes

• Fixed ImportError crash in slim docker (missing is_already_optimized)
• Fixed hardened image detection never matching Chainguard/distroless registries

New Features

• Configuration file (.slimrc.toml) — exclusions, default flags, per-ecosystem settings
• slim clean — scan and remove cache directories (__pycache__, .pytest_cache, .mypy_cache, etc.)
• --fail-on-unused — non-zero exit code for CI pipelines
• Declared dependency parsing — reads requirements.txt / pyproject.toml, warns on mismatches
• Transitive dependency analysis — classifies packages as direct, transitive, or unused
• --verbose / --quiet global flags, --exclude for scan and prune
• Pre-commit hooks and GitHub Actions workflow template

Performance

• Replaced pip freeze subprocess with importlib.metadata (instant)
• Node.js scanner line lookup optimized from O(n*m) to O(m log n)
• Import-to-package mappings expanded from 15 to 55+ entries
