Description
As a general comment (I don't think it needs to be addressed for this PR to be merged, just would be nice to have): Bazel can sometimes take a long time (e.g. a cold build of OpenTitanTool), it would be nice if these Bazel logs could be streamed as well as captured so that the user knows that something is still going on and the script hasn't locked up.
But I'm aware that will require hacking around with e.g. subprocess.Popen and manually handling the different streams, so may be more effort than it's worth at the moment 😅

Research direction
Start with the alert classification validation script and locate the Bazel invocation that currently captures its output. Check how its subprocess streams are handled; done means Bazel logs remain captured for validation while also being streamed so users can see progress during long builds.
