Render the S3 objectstore config (templates/config/objectstore.config.php.j2) into NC's config dir before install, gated on objstore.enabled — NC cannot switch an already-installed instance to objectstore primary storage, so it must be present at install time.
Add the SeaweedFS consumer storage Playwright test (files/playwright/test-seaweedfs.js, playwright.env.j2 SEAWEEDFS_* vars, spec wiring; drop the playwright-service-flag nocheck for the seaweedfs service) plus the shared runSeaweedfsStorageCheck helper (admin logs into the Filer once, counts bucket objects via the Filer JSON listing, asserts growth) and the seaweedfs-consumer integration lint.
web-app-seaweedfs: bind weed to 0.0.0.0 (-ip.bind) so the multi-homed gateway is reachable by consumers that resolve the service name to its IP on the shared network.
nextcloud_install: classify 'was not found on the appstore' as unavailable (skippable, non-fatal) so a plugin without a release for the pinned NC version does not abort the whole deploy.
