Research direction
Start by reading the repository's existing rule implementations and their tests to find how assignment patterns are detected and reported. Add coverage for assignments that initialize multiple variables on one line, preserving the requested bad and good examples. Done means the rule consistently rejects the bad form and accepts separate assignments.
