name: wai-quantum docs, course and locales

# The WAI Quantum documentation, the circuits course and the translations:
#   - docs: wai/tools/quantum-docs/ci.sh builds the command line, the job service and
#     the Python package from this checkout, starts a service, and runs check_docs.py
#     over every page docs.json names (the READMEs and docs pages of the engine, the
#     command line, the service, Python, the Studio, the desktop app, the editors and
#     the providers, the course's lessons, the agent skill, and their translations):
#     every block marked runnable run, every shown output held to the real one, every
#     receipt a block writes verified, the Rust blocks built and run, every block that
#     cannot run checked for the commands and flags it names, every `wai-quantum …` in
#     the prose a real command, every relative link a file, every dependency shown one
#     this repository's version satisfies, and every translation holding its English
#     page's code;
#   - course: engine::course's tests (every lesson's solution passes its own exercise
#     by proof or evidence, every known wrong answer fails it for its stated reason,
#     no hint or lesson gives the solution, every locale has every text and message)
#     and the command line's course and locale tests, each required by name;
#   - locales: every key of the Studio's words in every locale, with the same
#     placeholders, each translation marked machine-assisted (no browser).
# The Studio's course in the browser, in both languages, is in wai-quantum-studio.yml.
