BufferCell class Core

A single character cell in the terminal UI buffer.

Each BufferCell represents one printable cell on the terminal grid, holding a character, foreground/background color, and font styling. This is the fundamental unit used by the rendering engine to track visual content.

The cell is mutable and can be cleared or compared to others for optimized redraws or diffing purposes.
