Version 0.8.26 also continuously flicker on Windows 10

Fixed in v0.8.27 (releasing shortly).

The viewport-reset sequence emitted on TurnComplete / focus-gain / resize was double-clearing the screen (raw \x1b[2J\x1b[3J immediately followed by ratatui's own terminal.clear()), which Ghostty, the VSCode integrated terminal, and Win10 conhost render as visible flicker. v0.8.27 drops the destructive part; the alt-screen buffer's double-buffering plus ratatui's diff renderer handle the repaint cleanly. Terminals that were already flicker-free (macOS Terminal.app, iTerm2, alacritty) remain so.

Once v0.8.27 ships, please update with one of:

• npm: npm install -g deepseek-tui@latest
• brew: brew upgrade deepseek-tui
• cargo: cargo install --force deepseek-tui-cli

Reopen if you still see flicker after upgrading. Thanks for the report!
