- Refactor bots table to use owner_id foreign key relationship with users
- Add is_bot and bot_owner_id columns to users table for bot account tracking
- Add bot_id foreign key to posts table for bot-generated content tracking
- Create database indexes on owner_id, bot_id, is_bot, and bot_owner_id for query performance
- Remove bot handle, bio, avatar_url, and cryptographic keys from bots table (moved to user accounts)
- Update bot_content_sources schema and remove fetch_interval_minutes column
- Fix bot_content_items foreign key constraint with set null on delete
- Remove hardcoded NODE_NAME and NODE_DESCRIPTION from environment configuration
- Update admin panel, bot settings, and layout components to support new schema
