feat: implement DEC mode 2026 synchronized output to reduce terminal flicker

- Server wraps SSE terminal batches with DEC 2026 sync markers
- Client extracts and strips markers, writes atomically via RAF batching
- Native terminals (WezTerm, Kitty, etc.) get full sync support
- xterm.js web gets application-layer sync via marker extraction
