Scope CI/CD to build+test only; clean up runner infra

Remove automated deploy — Portainer handles deployments for now.
build.yml: deploy job removed, only builds and pushes image to registry.
infra/runner-compose.yml: clean standalone Portainer stack for act_runner,
  no swarm network dependency, uses external Forgejo URL.
infra/runner-swarm.yml: removed (replaced by runner-compose.yml).

-# Forgejo Actions runner — add these services to your existing Forgejo stack.
-#
-# Since the runner is in the same swarm as Forgejo it can:
-#   - Reach Forgejo at http://forgejo:3000 (no Traefik hop)
-#   - Use the host Docker socket (manager node) to build images and update services
-#   - Deploy the app via `docker service update` — no SSH needed
-#
-# The runner MUST run on a swarm manager node so it can call the Docker service API.
-# On a single-node swarm this is automatic. On multi-node, the placement constraint
-# below ensures it.
-#
-# One-time setup:
-#   1. Get a registration token:
-#      https://git.fabledsword.com → Site Administration → Runners → Create Runner
-#
-#   2. Add RUNNER_TOKEN to your stack's env file (same .env Forgejo uses):
-#      echo 'RUNNER_TOKEN=your_token_here' >> /path/to/forgejo.env
-#
-#   3. Redeploy the Forgejo stack to pick up the new services:
-#      docker stack deploy -c forgejo-stack.yml --with-registry-auth forgejo
-#
-# Docker Swarm does not support bind-mounts of /var/run/docker.sock via
-# `docker stack deploy`. Deploy using docker compose instead (still managed,
-# just not as a formal stack):
-#   docker compose -f forgejo-stack.yml up -d
-#
-# Required secrets in Forgejo (repo → Settings → Secrets → Actions):
-#   REGISTRY_USER    — your Forgejo username
-#   REGISTRY_TOKEN   — Forgejo PAT with write:packages scope
-#   DEPLOY_SERVICE   — full swarm service name for the app, e.g. fabledassistant_app
