This patch refines gccrs’s unused_assignment linting logic to correctly identify unused variables. It ensures that only the most recent assignment to a variable is tracked. If a variable is assigned a new value before the previous assignment has been used, the older assignment is now correctly flagged as potentially unused, preventing false positives. This addresses a bug where previous assignments might be overlooked.
