feat: Add Issue #503 - Audio pipeline with Jabra SPEAK 810

Implement full audio pipeline with:
- Jabra SPEAK 810 USB audio I/O (mic + speaker)
- openwakeword 'Hey Salty' wake word detection
- whisper.cpp GPU-accelerated STT (small/base/medium/large models)
- piper TTS synthesis and playback
- Audio state machine: listening → processing → speaking
- MQTT status and state reporting
- Real-time latency metrics tracking

ROS2 Topics Published:
- /saltybot/speech/transcribed_text: STT output for voice router
- /saltybot/audio/state: Current audio state
- /saltybot/audio/status: JSON metrics with latencies

MQTT Topics:
- saltybot/audio/state: Current state (listening/processing/speaking)
- saltybot/audio/status: Complete status JSON

Configuration parameters in yaml:
- device_name: Jabra device pattern
- wake_word_threshold: 0.5 (tunable)
- whisper_model: small/base/medium/large
- mqtt_enabled: true/false with broker config

+# Audio Pipeline (Issue #503)
+
+Comprehensive audio pipeline for Salty Bot with full voice interaction support.
+
+## Features
+
+- **Hardware**: Jabra SPEAK 810 USB audio device integration
+- **Wake Word**: openwakeword "Hey Salty" detection
+- **STT**: whisper.cpp running on Jetson GPU (small/base/medium/large models)
+- **TTS**: Piper synthesis with voice switching
+- **State Machine**: listening → processing → speaking
+- **MQTT**: Real-time status reporting
+- **Metrics**: Latency tracking and performance monitoring
+
+## ROS2 Topics
+
+Published:
+- `/saltybot/speech/transcribed_text` (String): Final STT output
+- `/saltybot/audio/state` (String): Current audio state
+- `/saltybot/audio/status` (String): JSON metrics with latencies
+
+## MQTT Topics
+
+- `saltybot/audio/state`: Current state
+- `saltybot/audio/status`: Complete status JSON
+
+## Launch
+
+```bash
+ros2 launch saltybot_audio_pipeline audio_pipeline.launch.py
+```
+
+## Configuration
+
+See `config/audio_pipeline_params.yaml` for tuning:
+- `device_name`: Jabra device
+- `wake_word_threshold`: 0.5 (0.0-1.0)
+- `whisper_model`: small/base/medium/large
+- `mqtt_enabled`: true/false
