Initial commit of Gemini Code CLI

This commit introduces the initial codebase for the Gemini Code CLI, a command-line interface designed to facilitate interaction with the Gemini API for software engineering tasks.

The code was migrated from a previous git repository as a single squashed commit.

Core Features & Components:

*   **Gemini Integration:** Leverages the `@google/genai` SDK to interact with the Gemini models, supporting chat history, streaming responses, and function calling (tools).
*   **Terminal UI:** Built with Ink (React for CLIs) providing an interactive chat interface within the terminal, including input prompts, message display, loading indicators, and tool interaction elements.
*   **Tooling Framework:** Implements a robust tool system allowing Gemini to interact with the local environment. Includes tools for:
    *   File system listing (`ls`)
    *   File reading (`read-file`)
    *   Content searching (`grep`)
    *   File globbing (`glob`)
    *   File editing (`edit`)
    *   File writing (`write-file`)
    *   Executing bash commands (`terminal`)
*   **State Management:** Handles the streaming state of Gemini responses and manages the conversation history.
*   **Configuration:** Parses command-line arguments (`yargs`) and loads environment variables (`dotenv`) for setup.
*   **Project Structure:** Organized into `core`, `ui`, `tools`, `config`, and `utils` directories using TypeScript. Includes basic build (`tsc`) and start scripts.

This initial version establishes the foundation for a powerful CLI tool enabling developers to use Gemini for coding assistance directly in their terminal environment.
