Rerun clang-format on the repo (#1217)

🚨 clang-format changes output per version!

This is with version 19.0.0. The modifications seem to be fixing the old
version’s errors - mainly involving omitted whitespace around binary ops
and inserted whitespace between goto labels and colons (if followed by a
curly brace.)

Also fixes a few mistakes made by e.g. someone (ahem) forgetting to pass
his ctl/string.h modifications through it.

We should add this to .git-blame-ignore-revs once we have its final hash
on master.
