laya-go: Go server plus agent CLI and MCP for Laya decisions

# Laya Go

English | [中文](README.zh.md)

Open horizontal **System 1** decision models for agents. Laya does **not** generate text. It scores structured features once and returns ranked pattern probabilities in microseconds to milliseconds. This repo is the Go **server + agent integration** that replaces legacy **JEV**.

**How to use:** run `laya-deploy` (default `0.0.0.0:7710`). Agents call `decide` via MCP, HTTP, or CLI and take `top.id` as the action.

## 30-second start

**Deploy host (Administrator PowerShell):**

```powershell
git clone https://github.com/neko233-com/laya-go.git
cd laya-go
.\deploy\install-service.ps1 -Port 7710
```

Service `LayaDeploy` listens on `0.0.0.0:7710` (model API + admin UI in one process).

**Local or teammate machines (agent access):**

```powershell
.\deploy\install-mcp.ps1 -Url http://127.0.0.1:7710
# teammates: use the deploy host IP, e.g. http://192.168.x.x:7710
```

**Restart** Codex / MiMo / Claude. MCP tool name: `laya`.

**Verify:**

```sh
curl -s http://127.0.0.1:7710/health
curl -s http://127.0.0.1:7710/v1/decide -H 'content-type: application/json' \
  -d '{"features":{"intent_change":0.9,"target_known":0.8},"top_k":3}'
```

Admin dashboard: `http://127.0.0.1:7710/admin` (use the deploy host IP on LAN).
