fix: Make tests pass and update documentation

- Fix config.py to ignore extra environment variables (docker-compose compatibility)
- Create PortableJSON type for SQLite/PostgreSQL compatibility in tests
- Replace JSONB and ARRAY types with PortableJSON in models
- Add ensure_utc() helper to handle timezone-naive datetimes from SQLite
- Fix timezone issues in mood_service, relationship_service, and self_awareness_service
- Fix duplicate code in test_providers.py
- Update CLAUDE.md with comprehensive Living AI documentation
- Add testing section with commands and setup details
- All 112 tests now pass successfully

+#### Services (`services/`)
+- `mood_service.py` - Valence-arousal mood model with time decay
+- `relationship_service.py` - Relationship scoring (stranger to close friend)
+- `fact_extraction_service.py` - Autonomous fact learning from conversations
+- `opinion_service.py` - Bot develops opinions on topics over time
+- `self_awareness_service.py` - Bot statistics and self-reflection
+- `communication_style_service.py` - Learns user communication preferences
+- `proactive_service.py` - Scheduled events (birthdays, follow-ups)
+- `association_service.py` - Cross-user memory associations
+
+#### Models (`models/living_ai.py`)
+- `BotState` - Global mood state and statistics per guild
+- `BotOpinion` - Topic sentiments and preferences
+- `UserRelationship` - Per-user relationship scores and metrics
+- `UserCommunicationStyle` - Learned communication preferences
+- `ScheduledEvent` - Birthdays, follow-ups, reminders
+- `FactAssociation` - Cross-user memory links
+- `MoodHistory` - Mood changes over time
+
+#### Mood System
+Uses a valence-arousal model:
+- Valence: -1 (sad) to +1 (happy)
+- Arousal: -1 (calm) to +1 (excited)
+- Labels: excited, happy, calm, neutral, bored, annoyed, curious
+- Time decay: Mood gradually returns to neutral
+
+#### Relationship Levels
+- Stranger (0-20): Polite, formal
+- Acquaintance (21-40): Friendly but reserved
+- Friend (41-60): Casual, warm
+- Good Friend (61-80): Personal, references past talks
+- Close Friend (81-100): Very casual, inside jokes

 ### Configuration
 All config flows through `config.py` using pydantic-settings. The `settings` singleton is created at module load, so env vars must be set before importing.
