Enum LimitSource 

#[non_exhaustive]
pub enum LimitSource {
    User,
    Endpoint,
    Preset,
}

限额数字的来源。

🔴 调用方必须据此区别对待：端点上报的可以直接用，静态兜底的应当让用户能改。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

用户在界面上手填的 —— 优先级最高。

端点报的也可能不对（中转站按套餐另有限制却照抄模型标称值）， 这时唯一的出口是让用户改；改了就必须压过端点值，否则改了等于没改。

Endpoint

端点在 /models 响应里自己报的 —— 最可信，包含中转站的真实限制

Preset

本 crate 的预置静态值 —— 保守估计，可能过时，应允许用户覆盖

Implementations

impl LimitSource

pub const fn as_str(self) -> &'static str

规范字符串，与 serde 线格式一致。调用方持久化来源时用它。

pub fn parse(s: &str) -> Option<Self>

从 Self::as_str 的产物解析回来；认不出返回 None。
