- Implemented a new SQL query to retrieve usage statistics by model and agents for a specific flow.
- Added corresponding Go types and methods to handle the new query in the database layer.
- Updated GraphQL schema to include the new ModelAgentsUsageStats type and the usageStatsByModelAgentsForFlow query.
- Enhanced frontend components to display the new usage statistics in the flow dashboard.
Adds conditional chain normalization in processChain to preserve reasoning cache when provider unchanged while fixing incomplete tool_calls and converting IDs when switching providers. Extends GraphQL API with modelProvider parameter for seamless provider changes without restart.
