Code Review

This pull request, which appears to be an automated dependency upgrade, modifies the .node-version file. The new version, 25.8.0, is not a valid Node.js version. This is a critical concern as it could indicate a configuration error that will break the build. If the file is intended for a different tool, its name is misleading and poses a significant maintainability risk. Please see the specific comment for details.

The file name .node-version and the pull request title suggest this change is to upgrade the Node.js version. However, neither the old version (25.7.0) nor the new version (25.8.0) are valid Node.js versions.

• If this file is indeed for specifying the Node.js version, this is an invalid version number and will break any environment (local or CI/CD) that tries to install it. Please correct it to a valid Node.js version (e.g., from the 20.x LTS line or 22.x current line).
• If this file is for a different tool, the file name is dangerously misleading and should be changed to reflect the tool it's versioning (e.g., .tool-name-version) to avoid confusion and potential build breakages in the future.

Given the potential to break builds, this needs to be addressed.
