"""Compute a ``size/{XS,S,M,L,XL}`` label for a PR from its changed files.

Reads the GitHub ``pulls/{n}/files`` JSON array on stdin (objects with
``filename``, ``additions``, ``deletions``) and prints the size label. Lock
and generated files are excluded so a dependency bump does not inflate the
size. Pure stdlib so it runs without an install and is unit-tested directly.
