v0.2.0

Major Improvements

• 🎯 Enhanced color deduction algorithm finds more optimal colors
• 🎨 Tie-breaker logic prefers colors furthest from background when reconstruction quality is equal
• 🧪 Expanded test coverage including mixed mode tests (e.g., --fg fff auto auto)
• 🚀 Better handling of complex images with gradients and strokes

Algorithm Improvements

• Increased candidate thresholds for better color selection:
  • 2 unknowns: 20 → 30 candidates
  • 3 unknowns: 20 → 25 candidates (full search) or 20 (selected)
• Fixed handling of 3 unknowns with many candidates
• Extracted magic numbers into named constants for better maintainability
• Improved documentation explaining the tie-breaker logic

Test Improvements

• Added translucent recovery tests for strict mode with mixed colors
• Renamed "fully_auto" tests to "non_strict" for clarity
• Updated README to use --release flag by default for better test performance
• Fixed test assertion messages to use consistent format

The algorithm now correctly finds pure/saturated colors when they provide the best reconstruction, achieving > 95% similarity in complex test cases.
