"""SimpleFarm 统一入口。

一个进程管两件事：**服务器**（后台常驻，人多人在线）和**客户端**（你自己玩、或者脚本/AI 调接口）。

快速开始
--------
    uv sync                            # 建好环境（只有服务端需要第三方依赖）
    uv run main.py serve --daemon      # 后台启动小型游戏服务器
    uv run main.py play                # 打开终端界面玩自己的牧场
    uv run main.py play --farm alice   # 换个牧场名就是另一个玩家
    uv run main.py status              # 看服务器状态
    uv run main.py stop                # 优雅停机（会把所有牧场存档）

给脚本 / AI 用的
----------------
    uv run main.py actions                    # 我当前能做哪些事
    uv run main.py do plant '{"plot":1,"crop":"wheat"}'
    uv run main.py state --json               # 完整状态（机器可读）
    uv run main.py watch                      # 实时滚动状态与日志
    uv run main.py bot --farm ai-1            # 让规则机器人替你经营一个牧场
    curl http://127.0.0.1:8765/api/actions    # 直接打接口也行

浏览器打开 http://127.0.0.1:8765/ 可以看到网页版客户端。

没装 uv？用 `python main.py ...` 效果完全一样，命令里的 "uv run " 去掉即可。

快速开始
--------
  0. 建好环境（只有服务端需要依赖）  uv sync
  1. 启动服务器（后台常驻）          uv run main.py serve --daemon
  2. 打开网页客户端                  http://127.0.0.1:8765/
  3. 终端里玩自己的牧场              uv run main.py play --farm 你的名字
  4. 让 AI / 机器人一起玩            uv run main.py bot --farm ai-1
  5. 收工                            uv run main.py stop

改代码之后跑这些
----------------
  uv run ruff check .        # 静态检查（未用导入、可疑写法……）
  uv run ruff format .       # 统一格式
  uv run pyright             # 类型检查

直接调接口（AI / 脚本）
-----------------------
  curl 'http://127.0.0.1:8765/api/actions?farm=default'
  curl -X POST 'http://127.0.0.1:8765/api/actions?farm=default' \\
       -H 'Content-Type: application/json' \\
       -d '{"action":"plant","params":{"plot":1,"crop":"wheat"}}'

  uv run main.py actions              # 我当前能做什么
  uv run main.py do harvest '{"plot":1}'
  uv run main.py state --json         # 机器可读的完整状态
  uv run main.py watch                # 实时看别人/机器人玩

SSE 实时推送（只读）
--------------------
  curl -N 'http://127.0.0.1:8765/api/stream?farm=default'
  服务器在状态变化时推 {"type":"state", ...}，每帧一行 data: JSON；
  没有消息时每 15 秒发一行 ": keep-alive" 心跳。
  写操作走 HTTP：POST /api/actions，两条路改的是同一个引擎。
