Unclear if this truly goes and grabs stuff from the compdb.

Unless there's a clang-format analogue, we may just want to stick with:

• clang-format -i for fmt
• run-clang-format for fmt-check
• clang-tidy --fix --fix-erors for tidy
• clang-tidy for tidy-check

run-clang-tidy pulls in clang-apply-replacements, which is already in the container and common.ninja
