feat(#128): add LlmProviderInstance Prisma schema
Added database schema for LLM provider instance configuration to support
multi-provider architecture.
Schema design:
- LlmProviderInstance model with UUID primary key
- Fields: providerType, displayName, userId, config, isDefault, isEnabled
- JSON config field for flexible provider-specific settings
- Nullable userId: NULL = system-level, UUID = user-level
- Foreign key to User with CASCADE delete
- Added llmProviders relation to User model
Indexes:
- user_id: Fast user lookup
- provider_type: Filter by provider
- is_default: Quick default lookup
- is_enabled: Enabled/disabled filtering
Migration: 20260131115600_add_llm_provider_instance
- PostgreSQL table creation with proper types
- Foreign key constraint
- Performance indexes
Prisma client regenerated successfully.
Database migration requires manual deployment when DB is available.
Fixes #128
