feat: TTS personality engine (Issue #494)

Browse Source 
Implement context-aware text-to-speech with emotion-driven expression for SaltyBot.

Features:
  ✓ Context-aware greetings (time of day, person names, emotion)
  ✓ Priority queue management (safety > social > idle)
  ✓ Emotion-based rate/pitch modulation (happy: faster+higher, sad: slower+lower)
  ✓ Integration with emotion engine (Issue #429) and TTS service (Issue #421)
  ✓ Configurable personality parameters
  ✓ Person recognition for personalized responses
  ✓ Queue management with 16-item buffer

Architecture:
  Node: tts_personality_node
    - Subscribes: /saltybot/tts_request, /saltybot/emotion_state, /saltybot/person_detected
    - Publishes: /saltybot/tts_command (formatted for TTS service), /saltybot/personality_state
    - Runs worker thread for asynchronous queue processing

Personality Parameters:
  - Name: "Luna" (default, configurable)
  - Speed modulation: happy=1.1x, sad=0.9x, neutral=1.0x
  - Pitch modulation: happy=1.15x, sad=0.85x, neutral=1.0x
  - Time-based greetings for 4 periods (morning, afternoon, evening, night)
  - Known people mapping for personalization

Queue Priority Levels:
  - SAFETY (3): Emergency/safety messages
  - SOCIAL (2): Greetings and interactions
  - IDLE (1): Commentary and chatter
  - NORMAL (0): Default messages

Files Created:
  - saltybot_tts_personality package with main personality node
  - config/tts_personality_params.yaml with configurable parameters
  - launch/tts_personality.launch.py for easy startup
  - Unit tests for personality context and emotion handling
  - Comprehensive README with usage examples

Integration Points:
  - Emotion engine (Issue #429): Listens to emotion updates
  - TTS service (Issue #421): Publishes formatted commands
  - Jabra SPEAK 810: Output audio device
  - Person tracking: Uses detected person names
