Unreleased

Tests for load_from_path, save_to_path, and parse_scheme_input config helpers
Tests for remove_config_at covering both existing and non-existent directories
Smoke test for print_color_scheme_preview
README documentation for color schemes: options table entry, dedicated section with all 5 schemes, first-run prompt note, and uninstall clarification

Extracted load_from_path, save_to_path, and parse_scheme_input as testable helpers in config.rs
Extracted remove_config_at as a testable helper in uninstall.rs

Five built-in color schemes for table output, selectable and persisted per user:
- default - GitHub-style SemVer severity (#D73A49 / #0366D6 / #28A745)
- okabe-ito - Color-blind safe Okabe-Ito palette (#E69F00 / #0072B2 / #009E73)
- traffic-light - Classic red/yellow/green (#E74C3C / #F1C40F / #2ECC71)
- severity - Monitoring/observability style (#8E44AD / #3498DB / #95A5A6)
- high-contrast - Maximum distinction, color-blind safe (#CC79A7 / #0072B2 / #F0E442)
All colors rendered with true-color (24-bit) escape codes for exact hex fidelity
--set-color-scheme flag: run without a value to preview all schemes visually, or pass a scheme name to save it permanently
Color scheme preference persisted to ~/.config/pycu/config.toml (Linux/macOS) or %APPDATA%\pycu\config.toml ( Windows)
First-run interactive prompt to choose a color scheme on initial install
--uninstall now also removes the pycu/ config directory

Check Python dependencies for newer versions on PyPI
Support for pyproject.toml (PEP 621 / uv), pyproject.toml (Poetry), and requirements.txt
Support for PEP 735 [dependency-groups] (used by uv)
Support for Poetry 1.2+ group dependencies ([tool.poetry.group.*.dependencies])
--upgrade / -u flag to rewrite the dependency file in-place with latest versions
--target / -t flag to filter updates by bump level (major, minor, patch)
--json flag for machine-readable output
--concurrency flag to control the number of concurrent PyPI requests (default: 10)
--self-update to update pycu itself to the latest release with SHA-256 checksum verification
--uninstall to remove pycu from the system
Color-coded output: red for major, blue for minor, green for patch bumps
Compound constraint handling (>=old,<bound updated intelligently)
Progress bar during PyPI lookups
Install scripts for Linux/macOS (install.sh) and Windows (install.ps1)
