Specify task name only when it cannot be derived from the struct name. Only append to the default name.

Device names ml-track-qc and m-l-track-q-c generated from the specified task name ml-track-qc and from the struct name MLTrackQC, respectively, differ in hyphenation. Consider fixing capitalisation of the struct name to MlTrackQc and removing TaskName.

Specified task name tree-creator-ele-ml-dda produces device name tree-creator-ele-ml-dda which does not match the device name tree-creator-electron-m-l-d-d-a from the struct name TreeCreatorElectronMLDDA. (Matching struct name TreeCreatorEleMlDda)

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: thollander/actions-comment-pull-request@v3. Actions will be forced to run with Node.js 24 by default starting June 16th, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

To tolerate certain issues in a directory, add a line with the test name in "o2linter_config".
