v0.1.4 — prebuilt Docker image on GHCR (closes #5)

Adds a GitHub Actions workflow that builds and pushes the Docker image
to ghcr.io/rgjorge/containerflow on every tag push, so end users can run
ContainerFlow without cloning the repo or building locally.

- New workflow: .github/workflows/docker-release.yml
- docker-compose.yml: uses the prebuilt image from GHCR by default
- New docker-compose.local.yml: override for building from source (devs)
- .env.example: simplified + adds COMPOSE_FILE toggle for local build
- README EN + ES: quick-start updated to no-clone flow
- .gitignore: ignore task/ planning notes dir

 ## Quick start
 
+No clone needed. Pull the prebuilt image from GHCR:
+
 ```bash
-git clone https://github.com/RGJorge/containerflow.git
-cd containerflow
+curl -O https://raw.githubusercontent.com/RGJorge/ContainerFlow/main/docker-compose.yml
+curl -O https://raw.githubusercontent.com/RGJorge/ContainerFlow/main/.env.example
 cp .env.example .env
 docker compose up -d
 ```
 
 Open `http://localhost:9470`. Done.
 
-For native development (hot reload): `bun install && bun run dev`.
+### Build from source instead
+
+If you cloned the repo and want to build locally (e.g. you modified the code):
+
+```bash
+git clone https://github.com/RGJorge/containerflow.git
+cd containerflow
+cp .env.example .env
+# In .env, uncomment: COMPOSE_FILE=docker-compose.yml:docker-compose.local.yml
+docker compose up -d --build
+```
+
+For native development (hot reload, no Docker): `bun install && bun run dev`.
