Pull request description:

  ## Issue being fixed or feature implemented

  These files always bounces around, and they are always created by unwanted paths. Let's hide them:

      Untracked files:
      (use "git add <file>..." to include in what will be committed)
          .claude/
          perf.data
          perf.data.old

  ## How Has This Been Tested?
  `git status` produce less noise

  ## Breaking Changes
