This commit adds support for 4-digit and 8-digit hexadecimal color codes
with alpha channel (e.g., #FF00FF80 for 50% transparent magenta).
Changes:
- Extended Color dataclass with optional alpha field (default 255)
- Updated _validate_color_hex to accept lengths 3, 4, 6, 8
- Updated from_hex to parse 4-digit (#RGBA) and 8-digit (#RRGGBBAA) hex codes
- Modified as_hex to return #RRGGBBAA when alpha != 255
- Added as_rgba() and as_bgra() methods
- Added from_rgba_tuple() and from_bgra_tuple() class methods
- Updated __eq__ and __hash__ to include alpha channel
- Added comprehensive unit tests for all RGBA functionality
- Updated docstrings with examples of new alpha channel support
