docs: lead Quick start with the published GHCR image

Running the app no longer requires cloning the repo: pull the
published ghcr.io image directly via docker-compose. Move the
build-from-source flow (existing docker-compose.yml + Dockerfile) to
a secondary section for contributors.

+You need [Docker](https://www.docker.com/) installed. That's it — no clone required, the image is published on GHCR.

+Create a `docker-compose.yml`:

+```yaml
+services:
+  app:
+    image: ghcr.io/jeangaston/lovelope:latest
+    ports:
+      - "3000:3000"
+    environment:
+      DATABASE_URL: "file:/app/data/askedout.db"
+      APP_URL: "http://localhost:3000"
+      GIPHY_API_KEY: "${GIPHY_API_KEY:-}"
+    volumes:
+      - ./data:/app/data
+    restart: unless-stopped
+```
+
+Then:
+
+```bash
+docker compose up -d
+```
+
+Open **http://localhost:3000**. Your data lives in `./data/askedout.db` on your machine.
+
+Want GIF search to work? Grab a free key at [developers.giphy.com](https://developers.giphy.com/), export it as `GIPHY_API_KEY` before running `docker compose up` (or drop it in a `.env` file next to `docker-compose.yml`), then restart. Without it, the app still runs fine, GIF search is just disabled.
+
+Pin a specific version instead of always tracking `latest` by using a release tag, e.g. `ghcr.io/jeangaston/lovelope:v0.1.0`.

+### Build from source

+If you'd rather build the image yourself instead of pulling from GHCR:

 git clone https://github.com/jeangaston/lovelope.git && cd lovelope
