Pi Talk Mode extension

A developer has built a "Talk Mode" extension for the Pi coding agent that prevents the AI from editing, creating, or modifying files. The extension, toggled with Shift+Tab, injects a system prompt that restricts the agent to read-only operations, analysis, and discussion while blocking any implementation actions. When active, the extension displays a "💬 talk" status indicator and prevents the AI from applying changes even if explicitly requested.
