* chore(ci): trigger ci workflow

* fix(ci): slugify image tag to match argocd branch_slug

Preview deployments were failing with ErrImagePull because CI pushed the
raw branch name (e.g. dependabot-github_actions-...) while the ArgoCD
ApplicationSet pulls docker.io/saidsef/node-webserver:{{branch_slug}},
which lowercases and replaces non-[a-z0-9-] chars with '-'. Slugify TAG
the same way so the pushed tag matches the tag ArgoCD resolves.
