Subject: [PATCH] refactor(core-ai): simplify model list to only Tatlock agent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes the "simple" fallback model and renames "pydantic" to "Tatlock"
to match the agent's British butler persona.

Changes:
- /models endpoint now returns only "Tatlock" model
- Removed "simple" model from advertised models
- Updated default model name from "pydantic" to "Tatlock"
- Updated health endpoint to show "Tatlock" agent status
- Added description: "PydanticAI agent with full tool support - your British butler assistant"

Benefits:
- Clearer model naming that matches agent persona
- Simplified model selection in Open WebUI
- Eliminates confusion between pydantic/simple models
- Consistent branding with Tatlock character

Open WebUI will now show only "Tatlock" as an available model, which uses
the full PydanticAI agent with tool calling capabilities.

Tested:
✅ /models endpoint returns only Tatlock
✅ Health check shows Tatlock as default agent
✅ Chat completions work with model="Tatlock"
✅ Tatlock persona responds correctly
