Summary

Every push to main currently puts the ESP32 workflow in the same concurrency group, so a new commit cancels the previous commit's jobs. In this job, the smoke test and all 16 optimized model cases passed, but the job was marked cancelled when another push arrived.

Use the concurrency group already shared by the other backend test workflows. Including the commit SHA for branch runs lets different main commits finish independently. The group also separates scheduled and manually triggered runs.

Authored with AI assistance using OpenAI Codex.

Test plan

git diff --check passed. Compared the complete concurrency block with all ten test-backend-*.yml workflows and verified that it matches each exactly. No emulator tests were rerun for this workflow scheduling change.
