feat: rewrite Output class with StyledChar[][] grid for correct emoji/wide char handling

Port Ink's output character model using @alcalzone/ansi-tokenize. Each cell is now a
StyledChar with proper grapheme clustering. Fixes emoji alignment, wide char boundaries,
and changes clipping to top-only (matching Ink). Upgraded ansi-tokenize to ^0.3.0.
