Add Ctrl+Shift+C keyboard shortcut for copying terminal text

Ctrl+C in the terminal sends SIGINT which cancels running Claude work.
This adds a custom key handler so Ctrl+Shift+C copies selected text to
the clipboard without interrupting the container.

 - **Base URL** — The URL of your Ollama server. Defaults to `http://host.docker.internal:11434`, which reaches a locally running Ollama instance from inside the container. For a remote server, use its IP or hostname (e.g., `http://192.168.1.100:11434`).
