Fix IPv6 connectivity failures: force IPv4 preference in CI builds

Mount ~/.config/opencode as a directory instead of individual files.
This persists all config changes (opencode.json, oh-my-opencode-slim.json,
skills) across container restarts. Add make to README architecture diagram.

 ## What's Included
 
+### Base image (`latest`)
+
 - **Debian bookworm-slim** — glibc, full terminal/PTY support
 - **opencode** — AI coding assistant
 - **Node.js 22** — for npx-based MCP servers
 - **AWS CLI v2** — SSO and Bedrock authentication
-- **Dev tools** — git, git-lfs, ssh, ripgrep, fd, fzf, jq, curl, wget, vim, tree
+- **Dev tools** — git, git-lfs, ssh, ripgrep, fd, fzf, bat, eza, zoxide, jq, make, curl, wget, neovim 0.12, tmux, htop, tree
 - **Non-root user** — runs as `developer` with UID auto-matched to workspace owner (sudo available)
 
+### OMOS image (`latest-omos`)
+
+Everything in the base image, plus:
+
+- **[oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim)** — multi-agent orchestration plugin
+- **Bun** — JavaScript runtime required by oh-my-opencode-slim
+- **6 specialized agents** — Orchestrator, Explorer, Oracle, Librarian, Designer, Fixer
+
+### Additional runtimes (build from source)
+
+When [building from source](https://gitea.jordbo.se/joakimp/opencode-devbox), additional runtimes are available via build args:
+
+- **Python 3** (`INSTALL_PYTHON=true`) — Python 3 + pip + venv
+- **Go** (`INSTALL_GO=true`) — Go toolchain
+
+## 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
+
+If you mount the opencode config directory (see Custom opencode Config above), the `oh-my-opencode-slim.json` file is included and persists across restarts. Edit it directly to control 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.

+## 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 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 in the base image) |
+| `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
+
+If you mount the opencode config directory (see Custom opencode config above), the `oh-my-opencode-slim.json` file is included and persists across restarts. Edit it directly to control 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:
