Subject: [PATCH] fix: alpine base image requires apk, not apt-get + root user
 for package installs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem: Forgejo runner base image is Alpine, not Debian.
-  doesn't exist (Alpine uses )
- Runner user is 1000, can't modify apk database (permission denied)
- CI workflow used GitHub-specific conditionals (contains() doesn't work in Forgejo)

Fixes:
1. Replace apt-get with apk for all runner Dockerfiles
2. Switch to USER root before package installation
3. Switch back to runner user (1000:1000) after
4. Simplify build workflow: build all runners in loop (no conditionals)

Testing:
✅ Golang runner: docker, node, npm installed
✅ Node runner: docker, node, npm installed
✅ Rust runner: docker, node, npm installed

This enables:
- homelab-frontend CI to build/push api-gateway image
- Build workflow to run on node runner with docker available
- All three runners have docker-cli for CI workflows
