Pull Request Overview

Adds support for finding and navigating to macro references in both the VSCode extension and the LSP server.

• Introduces Playwright tests for “Go to References” and “Find All References” on SQLMesh macros in the VSCode extension
• Extends LSP reference resolver with get_macro_find_all_references, integrates it into the generic get_all_references
• Updates sample SQL files and existing tests to include a new another_column for lineage/forking consistency
