Use keith/buildifier-action instead of non-existent Bazel target.
The previous target //tools/format:buildifier.check doesn't exist -
format_multirun only creates a format target, not a check target.

run: bazel build //...

- name: Test all targets

Let's skip this for now. Create an issue to track this. Add a code comment to do this within the build job after we check how to fix the buildifier, with the issue id.

- Add comment explaining ubuntu-latest is the standard runner
  (GitHub Actions doesn't offer ubuntu-slim)
- Remove || true from test step - CI should fail on test failures
- Remove format job, add TODO(#6) comment to track adding buildifier
  check once we determine the proper approach

PR description says CI should check BUILD file formatting with buildifier, but the workflow currently has only a TODO and no format check step. This repo already vendors buildifier via MODULE.bazel (buildifier_prebuilt) and exposes a formatter target at tools/format/BUILD.bazel:3-7 (//tools/format:format), so consider adding a CI step to run a check-mode formatter, or update the PR description/TODO to match the actual behavior.

For supply-chain hardening, consider pinning GitHub Actions to immutable commit SHAs (especially third-party actions like bazel-contrib/setup-bazel). Using floating tags (e.g., actions/checkout@v4, bazel-contrib/setup-bazel@0.9.1) allows upstream changes to affect your CI unexpectedly.
