Subject: [PATCH] ci: build & publish app + bot images to Gitea registry on
 merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a Gitea Actions workflow (.gitea/workflows/build-images.yml) that fires on
push to main (and workflow_dispatch). On the always-on ubuntu-latest runner it:

  - verifies the host Docker daemon is reachable (socket must be mounted)
  - logs into gitea.whitlocktech.com with a PAT (REGISTRY_USER / REGISTRY_TOKEN)
  - builds & pushes both images from the existing Dockerfiles, each tagged
    :latest and :sha-<7>:
      gitea.whitlocktech.com/<owner>/website-app  (./Dockerfile — server+client)
      gitea.whitlocktech.com/<owner>/website-bot   (./bot/Dockerfile)

Raw docker CLI (no marketplace actions) for portability on self-hosted Gitea;
the shared host daemon gives free layer caching between runs. Registry owner is
lowercased for Docker refs. Deploy (compose image: + pull) is a follow-up.

+# Build and publish the app + bot container images to Gitea's container registry
+# on every merge to main. Production then pulls prebuilt images instead of
+# building on the host.
+#
+# Prerequisites (one-time):
+#   • An always-on Gitea runner with label `ubuntu-latest` whose jobs have the
+#     host Docker socket mounted (/var/run/docker.sock), so `docker build` talks
+#     to the host daemon. This also gives free layer caching between runs.
+#   • Two repo secrets (Settings → Actions → Secrets):
+#       REGISTRY_USER  — the Gitea username that owns the token below
+#       REGISTRY_TOKEN — a Gitea access token with `write:package` (+ read:package)
+#     See the PR description / README for step-by-step token creation.
+#
+# Produces, in gitea.whitlocktech.com/<owner>/ :
+#   website-app:latest  + website-app:sha-<7>
+#   website-bot:latest  + website-bot:sha-<7>
