Provide a CI integration recipe (enforce BECs beyond the local hook)

[DataDave-Dev]

Context

becwright's promise is guaranteed enforcement, but the pre-commit hook can be bypassed with git commit --no-verify. There is no documented way to enforce BECs in CI, where it cannot be skipped — a real gap for the "deterministic safety net" positioning.

Proposal

Add a short, copy-pasteable CI recipe (start with GitHub Actions): a job that installs becwright (pipx install becwright or npm i -g becwright) and runs becwright check --all.

• Document it in documentation/usage.md (+ documentation/usage.es.md) and link from the README.
• Optionally ship it as a reusable composite action under integrations/.

Acceptance criteria

• A working example workflow + docs.
• The example demonstrably fails CI on a violating file.
