Class TerminalGridRenderer

Renders the visible portion of a TerminalScrollbackBuffer into a CellGrid. Handles line wrapping (word, character, or none, per the active TextWrapMode), scroll offset calculation, and per-line foreground coloring. Each scrollback line is wrapped to fit within the grid width, producing one or more visual rows.
