Release v1.4.2

Release v1.4.2

Makefiles prefer docker compose (V2) with docker-compose (V1) fallback
(REQ-MAKE-010). Optional monorepo update-deps includes (REQ-MAKE-009).
Demo Compose recipes go through the shell to avoid WSL Make execve EACCES.
Security checklist 12.4.1 reviewed.

Changelog

Changed

• Tooling (REQ-MAKE-010): Root and demo Makefiles prefer docker compose (V2) and fall back to docker-compose (V1); demo recipes invoke Compose via a shell helper to avoid WSL Make execve EACCES on the Docker Desktop CLI symlink.
• Tooling (REQ-MAKE-009): Monorepo update-deps Makefile includes are optional (-include) so standalone GitHub Actions checkouts do not fail.
