Use the same canonical subject identity as the syllabus.

Normalize PYQ units to the five-module syllabus contract.
The mapper performs exact matches against Unit ${module.number}. Arithmetic is tagged Unit 3 instead of module 2, I/O as Unit 4 instead of module 3, and values such as Unit 6 or Unit 6/5 are omitted or misrouted. Renumber to modules 1–5 and split or structurally represent mixed-unit questions.
