gsql2rsql

Analyze the transpiler codebase (especially renderer) for Separation of Concerns violations, document them with impact assessment, solutions, and create an action plan for refactoring. Note: Do not worry about deprecated features or backward compatibility; refactoring can be aggressive and breaking changes are acceptable.

guide an engineer (or an assistant-agent) through a transpiler bugfix. Emphasizes TDD, root-cause fixes (not workarounds), respect for the current Separation of Concerns, running the PySpark-focused tests, and verifying no regressions by running the non-PySpark test suite. The skill **must** ask the user immediately what they are trying to solve and which PySpark test(s) to run.

Implement new tests or improve existing tests for the gsql2rsql Cypher-to-SQL transpiler. Covers unit tests, integration tests, PySpark execution tests, golden file tests, and structural SQL assertions. Follows TDD principles and respects the 6-phase pipeline architecture.
