v0.3.0

Added

• Global Control Overrides: Introduced thread-safe set_override(level: ColorLevel) and clear_override() APIs, allowing developers to programmatically bypass environment cascades and explicitly lock down terminal styling preferences at runtime.

• Hex Color Construction: Added Color::from_hex(...) for creating RGB colors from "#RRGGBB" or "RRGGBB" hex strings, including support for compile-time const color definitions

• CSS Colors: Added CSSColor struct, providing the complete set of CSS named colors as Color constants. All standard 140 CSS color names and aliases are now available for convenient compile-time color selection.

• Panel Layouts: Added a generic Panel layout container supporting nested frames, custom titles, and automatic padding calculated via unicode-width.

Removed

• Apple Terminal Strikethrough Fallback: Removed the custom character-stitching fallback loop for macOS Terminal.app to resolve layout corruption, string data bloat, and ANSI tracking de-synchronization. The library now universally emits standard SGR 9 escape sequences across all environments.
