v0.3.0

🎉 Optional Output Argument

This release makes the output argument optional, simplifying the most common usage pattern!

✨ New Features

• Auto-generated output filenames: Simply run bgone input.png and get input-bgone.png
• Smart incremental naming: Automatically appends -bgone-1, -bgone-2, etc. when files exist
• Preserves file extensions: Works with .jpg, .png, or any format
• Fully backwards compatible: Explicit output paths still work as before

📖 Usage Examples

# Before: had to specify output
bgone input.png output.png --fg auto

# Now: output is optional!
bgone input.png --fg auto

# Still works with explicit output
bgone input.png custom-name.png --fg auto

🧪 Quality Improvements

• Added 7 comprehensive unit tests for output path generation
• All existing tests pass (77 tests total)
• Full test coverage for edge cases and incremental naming

🔧 Implementation Details

• Extension preservation and fallback to .png
• Automatic collision detection and resolution
• Supports up to 999 incremental files before erroring

This makes bgone even easier to use while maintaining all its powerful features!
