refactor: Enhance voice channel joining logic with retry mechanism and cleanup for existing players

- Updated interactionCreate event to improve error handling and logging.
- Enhanced ready event to ensure client user is available before proceeding.
- Refactored voiceStateUpdate event for better clarity and error handling.
- Adjusted index.ts to improve client initialization and command/event loading.
- Improved Shoukaku event handling and initialization in ShoukakuEvents.ts.
- Enhanced logger utility for better message formatting.
- Updated TypeScript configuration for better compatibility and strictness.
- Created a new botClient type definition for improved type safety.

-# discord-music-bot
+# Discord Music Bot (TypeScript)
 
-Discord bot made in Rust using serenity and lavalink-rs
+Discord music bot template written in TypeScript using `discord.js` and `shoukaku`, with Lavalink support.
+
+## Features
+
+- Slash commands (e.g., `/ping`, `/join`, `/play`, `/leave`)
+- `shoukaku` integration for robust Lavalink audio playback
+- Modular command and event handlers written in TypeScript
+- Basic Docker support (`Dockerfile`, `docker-compose.yml`)
+- Comprehensive test suite with Jest
+
+## Prerequisites
+
+- Node.js (>=16 recommended, check `package.json` for specific engine requirements)
+- pnpm (recommended) or npm
+- TypeScript (`typescript` package, usually installed as a dev dependency)
+- A Discord application with bot token and client ID
+- A running Lavalink server
+
+## Setup
+
+1.  **Clone the repository:**
+    ```sh
+    git clone <repository_url>
+    cd discord-music-bot
+    ```
+2.  **Install dependencies:**
+    ```sh
+    pnpm install
+    ```
+3.  **Configure Environment:**
+    Copy `.env.example` to `.env` and fill in your credentials:
+    ```dotenv
+    # Discord Bot Token (Required)
+    DISCORD_TOKEN=your_discord_bot_token
+
+    # Discord Application Client ID (Required for command deployment)
+    CLIENT_ID=your_discord_application_id
+
+    # Discord Guild ID (Optional, for deploying commands to a specific test server)
+    # GUILD_ID=your_guild_id_here
+
+    # Lavalink Configuration (Required)
+    LAVALINK_HOST=lavalink # Or 127.0.0.1 if running locally without Docker Compose
+    LAVALINK_PORT=2333
+    LAVALINK_PASSWORD=your_lavalink_password
+    # LAVALINK_SECURE=false # Set to true if Lavalink uses SSL/WSS
+
+    # Logging Level (Optional, defaults typically to 'info')
+    # LOG_LEVEL=info
+
+    # YouTube OAuth Token (Optional, needed for YouTube Music via specific plugins)
+    # See note below on how to obtain this.
+    YOUTUBE_OAUTH_TOKEN=your_youtube_oauth_token_here
+    ```
+
+    **Note on YouTube OAuth Token:**
+    The `YOUTUBE_OAUTH_TOKEN` is required by some Lavalink plugins (like the `youtube-plugin` potentially used here) to access YouTube Music tracks directly. Obtaining this involves:
+    1.  Go to the [Google Cloud Console](https://console.cloud.google.com/).
+    2.  Create a new project or select an existing one.
+    3.  Navigate to "APIs & Services" -> "Credentials".
+    4.  Click "Create Credentials" -> "OAuth client ID".
+    5.  Select Application type: **"TVs and Limited Input devices"**.
+    6.  Give it a name (e.g., "Lavalink YouTube Music Access").
+    7.  Click "Create". You'll get a Client ID and Client Secret (you likely won't need the secret directly for the token flow).
+    8.  Follow the on-screen instructions or Google's documentation for the "OAuth 2.0 for TV and Limited Input devices" flow. This usually involves visiting a specific URL with your client ID, getting a user code, authorizing the application on a separate device/browser logged into your Google account, and then exchanging the device code for a **refresh token**.
+    9.  Paste the obtained **refresh token** as the value for `YOUTUBE_OAUTH_TOKEN` in your `.env` file.
+
+4.  **Build TypeScript (if needed):**
+    Many setups use `ts-node` for development, but for production, you might need to compile:
+    ```sh
+    pnpm build # Check package.json for the exact build script
+    ```
+
+5.  **Register Slash Commands:**
+    Run the deployment script (ensure `CLIENT_ID` and `DISCORD_TOKEN` are set in `.env`).
+    ```sh
+    pnpm deploy # Check package.json for the exact deploy script (might be node/ts-node deploy-commands.ts)
+    ```
+
+6.  **Start the Bot:**
+    ```sh
+    pnpm start # Check package.json for the exact start script (might run compiled JS or use ts-node)
+    ```
+
+## Testing
+
+The project includes a comprehensive test suite using Jest. The tests cover commands, events, and utilities.
+
+### Running Tests
+
+```bash
+# Run all tests with coverage report
+pnpm test
+
+# Run tests in watch mode during development
+pnpm test:watch
+
+# Run tests in CI environment
+pnpm test:ci
+```

+### Coverage Requirements
+
+The project maintains high test coverage requirements:
+
+- Branches: 80%
+- Functions: 80%
+- Lines: 80%
+- Statements: 80%
+
+## Docker
+
+A `Dockerfile` and `docker-compose.yml` are provided for containerized deployment.
+
+-   Ensure your `.env` file is configured correctly.
+-   Build and run with Docker Compose:
+    ```sh
+    docker-compose up --build -d # Use -d to run in detached mode
+    ```
+-   The `docker-compose.yml` includes both the bot service and a Lavalink service.
