chore: install via pnpm + polyfill depuis Gitea (git-https) + lien local réactif

Passe l'installation de bun à pnpm (runtime/build/test restent bun).
Dépendance prod @ng-eventually/client résolue depuis le Gitea public en
git+https (committée, reproductible via pnpm-lock.yaml). Script
link:polyfill (S2 copie-overlay + watcher) pour un lien local réactif
préservant l'instance @ng-org unique. bun (peer de bun-plugin-tailwind)
approuvé au build (pnpm.onlyBuiltDependencies) pour que
node_modules/.bin/bun soit un vrai binaire. Dockerfile: install pnpm
avec git + node dans l'image, runtime bun inchangé. Doctrine tech-stack
(deployment, stack-and-commands) mise à jour.
