fix(NFC): bazel build

[c8ef]

Why

Current bazel build not work out of the box.

What is changing

1. in bazel 9, function like cc_test is not builtin, need to import from rules_cc.
2. the version bump in module.bazel is needed, some old version use old function parameter that does not exist in bazel 9.
3. the bazel format change is generated by buildifier.
4. the cpp file change is due to -Werror=sign-compare

LGTM.

Thanks for the review!

Will merge after CI gets green

I believe the related CI is now passing for macos bazel build and test, as well as linux bazel build (except for one test failure that I cannot reproduce on my own x86 machine). While some CI are already failing in the main branch, I am willing to investigate and address them in subsequent patches for better clarity and coherence.
