Add error handling to Docker Hub description update step

Integrate oh-my-opencode-slim as an opt-in feature via INSTALL_OMOS build arg.
A single build arg installs Bun, tmux, and the plugin; runtime activation is
controlled by ENABLE_OMOS and related env vars in the entrypoint.

+
+## oh-my-opencode-slim (OMOS variant)
+
+The `-omos` image variant includes [oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim), which adds a multi-agent layer on top of opencode. An Orchestrator delegates tasks to specialized agents, each configurable with different models and providers.
+
+### Quick start with OMOS
+
+```bash
+docker run -it --rm \
+  -e OPENAI_API_KEY=your-key \
+  -e OPENCODE_PROVIDER=openai \
+  -e ENABLE_OMOS=true \
+  -v ~/projects:/workspace \
+  -v ~/.ssh:/home/developer/.ssh:ro \
+  joakimp/opencode-devbox:latest-omos
+```
+
+On first start, the entrypoint configures oh-my-opencode-slim automatically. The default preset uses OpenAI models.
+
+### OMOS environment variables
+
+| Variable | Default | Description |
+|---|---|---|
+| `ENABLE_OMOS` | `false` | Activate oh-my-opencode-slim on container start |
+| `OMOS_TMUX` | `false` | Enable tmux pane integration (watch agents in split panes) |
+| `OMOS_SKILLS` | `true` | Install recommended skills (simplify, agent-browser, cartography) |
+| `OMOS_RESET` | `false` | Force regenerate config on next start (backs up existing config) |
+
+### Custom OMOS configuration
+
+Mount your own config to control which models power each agent:
+
+```bash
+docker run -it --rm \
+  -e ENABLE_OMOS=true \
+  -v ./oh-my-opencode-slim.json:/home/developer/.config/opencode/oh-my-opencode-slim.json:ro \
+  ... \
+  joakimp/opencode-devbox:latest-omos
+```
+
+See the [oh-my-opencode-slim configuration docs](https://github.com/alvinunreal/oh-my-opencode-slim/blob/master/docs/configuration.md) for the full reference.
+
+### Verifying agents
+
+After starting opencode with OMOS enabled, run inside the opencode session:
+
+```
+ping all agents
+```
+
+All six agents should respond if your provider authentication is working.

+## oh-my-opencode-slim (Multi-Agent Orchestration)
+
+[oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim) adds a multi-agent layer on top of opencode — an Orchestrator delegates tasks to specialized agents (Explorer, Oracle, Librarian, Designer, Fixer), each configurable with different models and providers.
+
+### Setup
+
+A pre-built OMOS image is available on Docker Hub as `joakimp/opencode-devbox:latest-omos`. Alternatively, build from source:
+
+**1. Build the image with OMOS support:**
+
+```bash
+docker compose build --build-arg INSTALL_OMOS=true
+```
+
+This installs Bun, tmux, and the oh-my-opencode-slim package into the image.
+
+**2. Enable in `.env`:**
+
+```bash
+ENABLE_OMOS=true
+```
+
+**3. Run as normal:**
+
+```bash
+docker compose run --rm devbox
+```
+
+On first start, the entrypoint runs the oh-my-opencode-slim installer in non-interactive mode. It generates agent configuration at `~/.config/opencode/oh-my-opencode-slim.json` inside the container. The default preset uses OpenAI models — edit the generated config or mount your own to customize.
+
+### OMOS Environment Variables
+
+| Variable | Default | Description |
+|---|---|---|
+| `ENABLE_OMOS` | `false` | Activate oh-my-opencode-slim on container start |
+| `OMOS_TMUX` | `false` | Enable tmux pane integration (tmux is included with `INSTALL_OMOS`) |
+| `OMOS_SKILLS` | `true` | Install recommended skills (simplify, agent-browser, cartography) |
+| `OMOS_RESET` | `false` | Force regenerate config on next start (backs up existing config) |
+
+### Custom Configuration
+
+You can mount your own oh-my-opencode-slim config instead of using the auto-generated one:
+
+```yaml
+volumes:
+  - ./oh-my-opencode-slim.json:/home/developer/.config/opencode/oh-my-opencode-slim.json:ro
+```
+
+The config file controls which models power each agent, fallback chains, council setup, and more. See the [oh-my-opencode-slim configuration docs](https://github.com/alvinunreal/oh-my-opencode-slim/blob/master/docs/configuration.md) for the full reference.
+
+### Verifying Agents
+
+After starting opencode with OMOS enabled, run inside the opencode session:
+
+```
+ping all agents
+```
+
+All six agents should respond if your provider authentication is working.
