Implement runtime font size and family changes via options proxy, matching xterm.js API behavior. Changes: - Wire up fontSize option changes to renderer.setFontSize() - Wire up fontFamily option changes to renderer.setFontFamily() - Add handleFontChange() helper that: - Clears active selection (pixel positions changed) - Resizes canvas to match new font metrics - Forces full re-render - Add tests for font change behavior Usage: term.options.fontSize = 20; // Dynamic resize term.options.fontFamily = 'Courier New'; Note: Font changes keep cols/rows constant (canvas grows/shrinks). Use FitAddon.fit() after font change to recalculate grid dimensions.
Standalone demo page that allows testing: - Font size changes via slider (8-32px) - Font family changes via dropdown - Refit to container after font change - Test pattern for visual verification Shows real-time metrics: cols, rows, cell dimensions, canvas size. No server required - works with just 'bun run dev'.
