trim trailing whitespace across branch (pre-commit auto-fix)

pre-commit's trailing-whitespace hook flagged 16 files on this branch
with stray trailing whitespace (mostly Makefiles, MLIR repeat_count
tests, and a couple of workflows + docs). Letting the hook fix them
so future pre-push runs are quiet.

No functional changes — whitespace only.
