Adopt the proven notify-bridge pipeline pattern and fix deployment bugs. Workflows: - build.yml: split into parallel frontend / backend / build-image jobs. Run svelte-check + vitest + `go vet ./...` + `go test ./internal/...` (tests were never executed in CI). Use buildx with GHA layer cache and pin Go to 1.25. Quote the `if:` skip-guard so it is valid YAML. - release.yml: gate the release on a passing test job, then build & push the image, then create the Gitea release LAST so a failed image build can no longer leave an orphan release. Use buildx + registry buildcache, a hard registry login (a push failure now fails the release), and auto-generate a changelog between tags. Docker: - Dockerfile: pin golang to 1.25 (matches go.mod's `go 1.25.0`), add BuildKit cache mounts for the module + build caches, an OCI source label, VOLUME /app/data, and a HEALTHCHECK on /readyz. - docker-compose.yml: fix the healthcheck — it targeted POST-only /api/auth/login (405 -> always unhealthy); now /readyz. Point the image name at the Gitea registry tag with build-from-source as the default. - .dockerignore: exclude ~95 MB of stray binaries, logs, env, and CI/doc files from the build context.
