📝 Update README with complete Docker run documentation 📝

Rewrite README.md to accurately reflect the container's three bundled
services (Gitea, dockerd DinD, act_runner) and all required runtime
details that were missing from the previous sparse version.
- README.md: add full description of Gitea + DinD + act_runner all-in-one image
- README.md: add --privileged note explaining DinD cgroup requirement
- README.md: document all four ports (80/7833/2375/44015) with service labels
- README.md: add volumes table (/config, /data) with descriptions
- README.md: add environment variables table (TZ, SERVER_ADDRESS, SERVER_TOKEN, RUNNER_LABELS, RUNNERS_START, RUNNERS_LOG_DIR)
- README.md: update docker-compose with all ports and privileged flag
- README.md: add docker-compose YYMM date tag convention note
- README.md: follow canonical section order (Docker → Development → License)

-## 👋 Welcome to gitea 🚀  
+# gitea
 
-gitea README  
+An all-in-one Alpine-based Docker image that bundles **Gitea** (self-hosted Git service), **Docker-in-Docker** (dockerd), and **act_runner** (Gitea Actions CI runner) into a single container. Designed for teams that want a complete self-hosted Git + CI/CD stack without orchestrating multiple containers. Gitea is pre-configured with Actions enabled, SSH access, LFS, and five act_runner worker instances that register automatically on first boot.
