README + DOCKER_HUB: lead with no-git-clone curl-template path

The previous Quick Start in both surfaces led with 'git clone',
which is overkill for users who just want to run the published image.
Match pi-devbox's pattern: lead with 'mkdir; curl docker-compose.yml;
curl .env.example; edit .env; docker compose run --rm devbox'. Keep
the git-clone path as 'for hackers/forkers'.

Required pre-step: make the gitea repo public so unauthenticated
curl to the raw URL works (done out of band — repo was private until
this commit landed).

 ## Quick Start
 
+For a fully-configured environment with persistent state (opencode config, mempalace memory, neovim plugins, bash history) surviving container recreation, use docker-compose. **You don't need to clone the repo** — just grab two template files:
+
+```bash
+mkdir -p ~/opencode-devbox && cd ~/opencode-devbox
+curl -O https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/docker-compose.yml
+curl -fsSL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/.env.example -o .env
+# Edit .env — set OPENCODE_PROVIDER, the matching API key,
+# WORKSPACE_PATH, GIT_USER_NAME, GIT_USER_EMAIL.
+docker compose run --rm devbox
+```
+
+This drops you straight into opencode with your project mounted at `/workspace`. Use `bash` as the command (e.g. `docker compose run --rm devbox bash`) to land in a shell first — useful for `aws sso login`, `pi` (on `*-with-pi` variants), or multi-harness workflows.

+**One-shot run, no persistence:**
