Say hello to a new level of interactivity in Gemini CLI

Gemini CLI v0.9.0 introduces pseudo-terminal (PTY) support, enabling interactive commands like vim, top, and git rebase -i to run directly within the CLI context. The update uses node-pty to spawn processes in a virtual terminal, streaming real-time snapshots of terminal state including text, colors, and cursor position. This architecture supports two-way communication with keyboard input and window resizing, eliminating the need to switch to separate terminals while maintaining full context awareness.
