The runner was alive all along (gitea/act_runner, ubuntu-latest label);
no run ever appeared because Gitea only reads .gitea/workflows/ (or
.github/workflows/) and ignores the .forgejo/ path the workflow shipped
under. The legacy repo's .gitea/workflows/check.yml was the clue.
References corrected (workflow header, TESTING.md, agent files); this
push doubles as the first live trigger of the workflow.
