Adds a new browser-fetch microservice that wraps Lightpanda for rendering
JS-heavy pages, and wires it into the knowledge URL parser as a fallback
when the upstream link reader returns 403/429/5xx for an allow-listed
domain (e.g. zhuanlan.zhihu.com). Includes config/env plumbing, hot-reload
diff support, and full deploy assets (Dockerfile target, docker-compose,
k3s manifests, image-build/package scripts).
CI workflows now own image publishing: backend-ci and frontend-ci push
service images to the Gitea Registry tagged with commit8. CD workflows
(nas-compose-deploy, nas-compose-service-deploy, offline-package, the
new nas-k3s-deploy) pull and verify those tags instead of rebuilding,
so deployments fail fast when CI hasn't produced the matching image.
The shared deploy/scripts/gitea-registry-images.sh helper drives both
the ensure (CI) and verify (CD) paths, and package.sh can now hydrate
its local images from the registry via SOURCE_IMAGE_REGISTRY.
