feat: add DaoXE as an OpenAI-compatible provider alias

Mirrors the OVHcloud alias-provider pattern: alias entry with DAOXE_API_KEY,
auto-config support, system-message merge behavior shared with the other
OpenAI-compatible gateway aliases, provider docs page, example recipe, and
test coverage across the touched packages. The models.dev catalog already
carries the daoxe entry, so the default model resolves through it.

+
+_Use DaoXE models with Docker Agent._
+
+## Overview
+
+[DaoXE](https://daoxe.com) is a multi-model LLM gateway that serves models from
+multiple vendors behind one OpenAI-compatible endpoint. Docker Agent includes
+built-in support for DaoXE as an alias provider.
+
+## Setup
+
+1. Create an API key from your DaoXE account dashboard.
+2. Set the environment variable:
+
+   ```bash
+   export DAOXE_API_KEY=your-api-key
+   ```
+
+## Usage
+
+### Inline Syntax
+
+```yaml
+agents:
+  root:
+    model: daoxe/<model-id>
+    description: Assistant using DaoXE
+    instruction: You are a helpful assistant.
+```
+
+### Named Model
+
+```yaml
+models:
+  daoxe_model:
+    provider: daoxe
+    model: <model-id>
+    temperature: 0.7
+    max_tokens: 8192
+
+agents:
+  root:
+    model: daoxe_model
+    description: Assistant using DaoXE
+    instruction: You are a helpful assistant.
+```
+
+## Available Models
+
+DaoXE's catalog is account-scoped and changes over time: new models appear as
+upstream vendors release them. List the model IDs your account can call with:
+
+```bash
+curl https://api.daoxe.com/v1/models \
+  -H "Authorization: Bearer $DAOXE_API_KEY"
+```
+
+Use any ID from that response as the `model` value. Docker Agent's default for
+DaoXE is `claude-sonnet-4-6`.
