Subject: [PATCH] ci(codspeed): only run walltime on walltime-labeled PRs or v*
 tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

walltime benchmarks are expensive — skip them in CI unless:
- the PR has a 'walltime' label, or
- triggered by a v* release tag

fix .gitattributes to use valid gitattributes syntax instead of
EditorConfig properties that were causing 'invalid attribute name'
warnings.
