Note

Low Risk
Low risk: build tooling/documentation only, with no production code changes. Main risk is minor developer friction if the new docs/command example is incorrect.

Overview
Introduces a new mise task, check, that depends on fmt, lint, and test:ci so contributors can run the full pre-CI suite via mise run check.

Updates CLAUDE.md to require mise run check before committing and documents its expanded equivalent, while also altering the lint/format example command.
