Identify which tests need rerunning after a code change — traces static call graph (function-level) or import graph (module-level) to find affected test files, then emits a ready-to-run pytest command. TRIGGER when: user asks which tests are affected by a change; phrases: \"which tests are affected\", \"what tests cover this\", \"test impact of\", \"what tests to rerun\".
