refactor: Transform daemon_boyfriend into Loyal Companion

Rebrand and personalize the bot as 'Bartender' - a companion for those
who love deeply and feel intensely.

Major changes:
- Rename package: daemon_boyfriend -> loyal_companion
- New default personality: Bartender - wise, steady, non-judgmental
- Grief-aware system prompt (no toxic positivity, attachment-informed)
- New relationship levels: New Face -> Close Friend progression
- Bartender-style mood modifiers (steady presence)
- New fact types: attachment_pattern, grief_context, coping_mechanism
- Lower mood decay (0.05) for emotional stability
- Higher fact extraction rate (0.4) - Bartender pays attention

Updated all imports, configs, Docker files, and documentation.
