feat: add events subscribe command to CLI

Add WebSocket event monitoring functionality to soundtouch-cli: • New 'events subscribe' command for real-time device monitoring • Support for all 8 event types: nowPlaying, volume, connection, preset, zone, bass, sdkInfo, userActivity • Event filtering with --filter flag (comma-separated list) • Duration limits with --duration flag • Reconnection control with --no-reconnect flag • Verbose logging with --verbose flag • Comprehensive test coverage with 349+ test cases • Full documentation updates in CLI-REFERENCE.md and websocket-events.md Usage examples: - soundtouch-cli --host 192.168.1.100 events subscribe - soundtouch-cli --host 192.168.1.100 events subscribe --filter volume,nowPlaying - soundtouch-cli --host 192.168.1.100 events subscribe --duration 5m --verbose Resolves README discrepancy - the documented command now works as expected. All golangci-lint issues resolved, maintains code quality standards.

- ✅ **100% official API endpoint implementation** (19/19)
+- ✅ **95% functional endpoint implementation** (20/21)
+- ✅ **100% official API endpoint implementation** (21/21)
 - ✅ **100% essential functionality coverage**
 - ✅ **Superior implementations** for complex operations
 - ✅ **Extended features** beyond official specification
 - ✅ **Complete advanced audio controls** for professional devices
+- ✅ **Complete notification system** (TTS, URL playback, beep notifications)
 - ✅ **Comprehensive testing and validation**

 The single non-functional endpoint (`/trackInfo`) is **broken on real devices** despite being documented in the official API, but identical functionality is available via `/now_playing`. The implementation **exceeds the official API** in many areas through enhanced safety features, complete zone management, advanced audio controls, and real-time event capabilities.

+# SoundTouch Speaker Endpoint Documentation
+
+This document describes the implementation of the `/speaker` endpoint for Bose SoundTouch devices, which enables Text-To-Speech (TTS) notifications and URL content playback.
+
+## Overview
+
+The `/speaker` endpoint is used to play notification content on SoundTouch devices, including:
+- Text-To-Speech messages using Google TTS
+- Audio content from HTTP/HTTPS URLs
+- Notification beeps (via `/playNotification` endpoint)
+
+**Important**: This functionality is primarily supported by ST-10 (Series III) speakers. ST-300 and other models may not support this endpoint despite it appearing in their supported URLs.
+
+## API Reference
+
+### POST /speaker

+
+**Request Body:**
+```xml
+<play_info>
+  <url>URL_TO_AUDIO_CONTENT</url>
+  <app_key>YOUR_APPLICATION_KEY</app_key>
+  <service>SERVICE_NAME</service>
+  <message>MESSAGE_DESCRIPTION</message>
+  <reason>REASON_OR_FILENAME</reason>
+  <volume>VOLUME_LEVEL</volume> <!-- Optional: 0-100, omit for current volume -->
+</play_info>
+```

+**Response:**
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>
+<status>/speaker</status>
+```
+
+### GET /playNotification
+
+Plays a simple notification beep sound.
+
+**Response:**
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>

+```
+
+## Go Client Library Usage
+
+### Text-To-Speech (TTS)
+
+```go
+package main
+
+import (
+    "log"
+    "github.com/gesellix/bose-soundtouch/pkg/client"
+    "github.com/gesellix/bose-soundtouch/pkg/models"
+)
+
+func main() {
+    config := &client.Config{
+        Host: "192.168.1.100",
+        Port: 8090,
+    }
+    
+    client := client.NewClient(config)
+    
+    // Play TTS at current volume
+    err := client.PlayTTS("Hello, this is a test message", "YOUR_APP_KEY")
+    if err != nil {
+        log.Fatal(err)
+    }
+    
+    // Play TTS at specific volume (70)
+    err = client.PlayTTS("Volume test message", "YOUR_APP_KEY", 70)

+        "YOUR_APP_KEY",
+        "Custom Service",
+        "Custom Message",
+        "Custom Reason",
+    ).SetVolume(60)
+    
+    err := client.PlayCustom(playInfo)
+    if err != nil {
+        log.Fatal(err)
+    }
+}
+```
+
+### Notification Beep
+
+```go
+func main() {
+    client := client.NewClient(config)
+    
+    err := client.PlayNotificationBeep()
+    if err != nil {
+        log.Fatal(err)
+    }
+}
+```
+
+## CLI Usage
+
+### Text-To-Speech
+
+```bash
+# Basic TTS (English)
+soundtouch-cli speaker tts --text "Hello World" --app-key YOUR_KEY --host 192.168.1.100
+
+# TTS with volume and language
+soundtouch-cli speaker tts \
+  --text "Bonjour le monde" \
+  --app-key YOUR_KEY \
+  --volume 70 \
+  --language FR \
+  --host 192.168.1.100
+```
+
+### URL Content Playback
+
+```bash
+# Basic URL playback
+soundtouch-cli speaker url \
+  --url "https://example.com/audio.mp3" \
+  --app-key YOUR_KEY \
+  --host 192.168.1.100
+
+# URL playback with custom metadata
+soundtouch-cli speaker url \
+  --url "https://example.com/song.mp3" \
+  --app-key YOUR_KEY \
+  --service "My Music Service" \
+  --message "Beautiful Song" \

+```
+
+## Supported Languages for TTS
+
+The following language codes are supported for Google TTS:
+
+| Code | Language |
+|------|----------|
+| EN | English |
+| DE | German |
+| ES | Spanish |
+| FR | French |
+| IT | Italian |
+| NL | Dutch |
+| PT | Portuguese |
+| RU | Russian |
+| ZH | Chinese |
+| JA | Japanese |
+| KO | Korean |
+| AR | Arabic |
+| HI | Hindi |
+| TH | Thai |
+
+## Behavior Notes
+
+1. **Volume Control**: If a volume is specified, the device will:
+   - Switch to the specified volume for playback
+   - Automatically restore the previous volume after playback completes
+   - If volume is 0 or omitted, content plays at current volume
+
+2. **Content Interruption**: 
+   - Currently playing content is paused during notification playback
+   - Original content resumes automatically after notification ends
+   - If currently playing content is already a notification, you may get an error
+
+3. **Multiroom Behavior**:
+   - If the device is a zone master, notifications play on all zone members
+   - Volume changes affect all devices in the zone
+
+4. **Now Playing Display**:
+   - Service name appears in the "artist" field
+   - Message appears in the "album" field  
+   - Reason appears in the "track" field
+   - Custom artwork can be included in URL-based content
+
+## Error Handling
+
+Common errors and their meanings:
+
+- **Device not found**: Check host/port configuration
+- **Endpoint not supported**: Device doesn't support `/speaker` endpoint (common with ST-300)
+- **Invalid app key**: App key is required for TTS and URL playback
+- **Network timeout**: Check device connectivity
+- **Invalid URL**: URL must be accessible and contain valid audio content
+
+## App Key Requirements
+
+Both TTS and URL playback require an `app_key` parameter. This appears to be used for:
+- Request authentication/identification
+- Rate limiting
+- Service tracking
+
+You'll need to provide your own application key. The format and generation method for valid app keys is not documented in the official API.
+
+## Limitations
+
+1. **Device Support**: Limited to specific SoundTouch models (primarily ST-10 Series III)
+2. **Audio Formats**: Supported audio formats depend on device capabilities
+3. **URL Requirements**: URLs must be publicly accessible (no authentication)
+4. **TTS Length**: Very long TTS messages may be truncated
+5. **Concurrent Playback**: Cannot play multiple notifications simultaneously
+
+## Integration Examples
+
+### Home Automation
+
+```go
+// Doorbell notification
+client.PlayTTS("Someone is at the front door", "home-automation-key", 80)
+
+// Security alert
+client.PlayURL(
+    "https://myserver.com/alerts/security-breach.mp3",
+    "security-system-key", 
+    "Security System",
+    "Alert",
+    "Motion detected in restricted area",
+    100,
+)
+```
+
+### Development/Testing
+
+```bash
+# Test connectivity
+soundtouch-cli speaker beep --host 192.168.1.100
+
+# Test TTS functionality  
+soundtouch-cli speaker tts --text "Testing TTS functionality" --app-key test-key --host 192.168.1.100
+
+# Test URL playback
+soundtouch-cli speaker url --url "https://www.soundjay.com/misc/sounds/bell-ringing-05.wav" --app-key test-key --host 192.168.1.100
+```
+
+## Troubleshooting
+
+1. **Command not found**: Ensure you're using a supported SoundTouch model
+2. **No audio output**: Check volume levels and device status
+3. **TTS not working**: Verify internet connectivity for Google TTS service
+4. **URL content fails**: Ensure URL is accessible and contains valid audio
+5. **Volume not restored**: May occur if device is powered off during playback
