docs: Update README and add Linux setup script

Improve documentation and add a setup script for easy deployment on Linux systems.

- Update README.md with instructions for the new multi-voice slash commands and the oices/ directory structure.
- Add a comprehensive 'Linux Server Deployment' section to the README, detailing both a quick setup via a new script and a manual systemd service setup.
- Create setup_linux.sh to automate dependency checking, virtual environment creation, and service installation on Linux.
- Revise comments in .env.example for clarity and to reflect the latest configuration options.

+## Linux Server Deployment
+
+To run the bot as a service on a Linux server:
+
+### Quick Setup (Recommended)
+
+```bash
+# Make the setup script executable
+chmod +x setup_linux.sh
+
+# Run the setup script
+./setup_linux.sh
+```
+
+The script will:
+- Check system dependencies (Python 3.10+, FFmpeg, pip)
+- Create a virtual environment and install dependencies
+- Create `.env` template if needed
+- Optionally install and configure the systemd service
+
+### Manual Setup
+
+1. **Install system dependencies**:
+   ```bash
+   # Ubuntu/Debian
+   sudo apt update
+   sudo apt install python3 python3-pip python3-venv ffmpeg
+   
+   # Fedora
+   sudo dnf install python3 python3-pip ffmpeg
+   
+   # Arch
+   sudo pacman -S python python-pip ffmpeg
+   ```
+
+2. **Set up the project**:
+   ```bash
+   cd /path/to/PocketTTSBot
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+3. **Configure the service**:
+   
+   Edit `pockettts.service` and replace:
+   - `YOUR_USERNAME` with your Linux username
+   - Update paths if your bot is not in `/home/YOUR_USERNAME/PocketTTSBot`
+
+4. **Install the service**:
+   ```bash
+   sudo cp pockettts.service /etc/systemd/system/
+   sudo systemctl daemon-reload
+   sudo systemctl enable pockettts  # Start on boot
+   sudo systemctl start pockettts   # Start now
+   ```
+
+### Service Management
+
+```bash
+# Check status
+sudo systemctl status pockettts
+
+# View logs (live)
+journalctl -u pockettts -f
+
+# View recent logs
+journalctl -u pockettts --since "1 hour ago"
+
+# Restart after changes
+sudo systemctl restart pockettts
+
+# Stop the bot
+sudo systemctl stop pockettts
+
+# Disable auto-start
+sudo systemctl disable pockettts
+```
+
+### Updating the Bot
+
+```bash
+cd /path/to/PocketTTSBot
+git pull  # If using git
+source venv/bin/activate
+pip install -r requirements.txt
+sudo systemctl restart pockettts
+```
