Replace the terse DEV.md with a comprehensive French-language guide
covering code standards, security rules, and the npm publish workflow.
Key changes:
- Expand code principles into readable prose (single responsibility,
control flow, input validation, promise handling, minimal scope)
- Add concrete security sections: parameterized queries, secret
management via env vars, dependency auditing, and opaque error
messages
- Document the full publish procedure (version bump, build, audit,
npm publish with provenance, git tag)
- Remove the NASA Power of Ten bullet list in favor of actionable,
project-specific guidelines
Replace the project directory tree and PR integration/versioning
sections with a new "Philosophie de développement" section covering
the NASA Power of Ten rules and security-by-design principles.
