Implement synchronized output mode (CSI ? 2026 h/l) which allows applications to batch terminal updates and render them atomically, preventing screen tearing during rapid output. Features: - BSU (CSI ? 2026 h) pauses rendering, buffering row updates - ESU (CSI ? 2026 l) flushes buffer and renders atomically - Configurable timeout via synchronizedOutputTimeout option (default 5s) - Exposed via terminal.modes.synchronizedOutputMode Closes #3375 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
