Module buffer 

Double buffering and cell-level diffing for flicker-free rendering. Maintains screen state to enable precise, minimal updates. Double buffering and cell-level diffing for flicker-free rendering.

This module implements a double-buffering system that maintains two complete representations of the terminal screen. By comparing these buffers cell-by-cell, we can generate minimal updates that eliminate flicker entirely.
