The workflow sat at `recognization/.github/workflows/`, but Actions only reads
`.github/workflows` at the repository root, so it never ran. Moved unchanged;
it already sets `working-directory: recognization`.
Verified locally with the same command the workflow runs:
`python -m unittest discover -s code -p 'test_*.py'` - 255 tests, OK, 2
real-model skips.
