Subject: [PATCH] ci: fix runner label - use 'rust' instead of non-existent
 'docker'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BUG FOUND: Workflow was requesting 'runs-on: docker' but Forgejo only has:
  - golang (golang:1.26-bookworm + dind)
  - rust (rust:1.83-bookworm + dind)
  - node (node:22-bookworm)

No 'docker' runner exists, so CI hung indefinitely waiting for unavailable runner.

FIX: Changed to 'runs-on: rust'
Rationale:
  ✅ Rust toolchain pre-installed (no cargo install needed)
  ✅ Docker-in-Docker available (for docker build + push)
  ✅ 2 CPU, 4GB RAM limits (sufficient for Rust builds)
  ✅ 1.83-bookworm base image (production-ready)
  ✅ Perfect for Rust projects

Result: CI will now acquire the correct runner and complete builds in 5-10 minutes

See .forgejo/README.md for runner reference guide

+**Runner Selection**:

+Workflow uses: `runs-on: rust`

+Available runners in Forgejo:
+- `golang` - golang:1.26-bookworm + dind (for Go projects)
+- `rust` - rust:1.83-bookworm + dind (✅ for Rust projects)
+- `node` - node:22-bookworm (for Node.js projects)

+Why `rust` for poimen-memory:
+- ✅ Pre-installed Rust toolchain
+- ✅ Docker-in-Docker (dind) for image builds
