Gitea Actions workflow running on every PR and push to main: pnpm
install with caching, workspace build, ESLint+Prettier, tsc, Vitest,
translation key parity, and docker builds of both images (build-only —
pushing is the CD workflow's job). Live verification of the red/green
PR gate follows once the act_runner from issue #9 is registered;
issue #7 stays open until then.
Part of #7
