Metric Lineage Tracking And Impact Analysis For Semantic Layer Changes

An open-source text-to-SQL and generative BI agent with a semantic layer. [#opensource](https://github.com/Canner/WrenAI)

Unique: Maintains a dependency graph of semantic layer definitions and tracks which queries/dashboards depend on specific metrics, enabling impact analysis before changes — this is distinct from simple documentation because it's automated and integrated with the query generation pipeline

vs others: More comprehensive than manual impact analysis because it automatically tracks all dependencies, and more actionable than static lineage documentation because it's integrated with the semantic layer and can predict impacts of changes
