运行时格式
按 codegen target 选择 runtime format：
[codegen.rust]
runtime_format = "sora"
Runtime format 是生成代码能加载的数据格式。它们对应导出格式：
Codegen runtime_format | Required Export |
|---|---|
sora | binary |
json | json |
cbor | cbor |
sora-protobuf | sora-protobuf |
这个设置不会改变 Excel、CSV、TOML、JSON、YAML 或 schema 文件。它只决定目标语言生成什么 loader。选定的 runtime format 必须在项目 build 中有匹配的 export。

依赖类型含义：
| Kind | Meaning |
|---|---|
| self-contained | 生成 runtime 内置 decoder。 |
| standard library | 生成 runtime 使用语言标准库。 |
| managed dependency | 生成 runtime 预期使用该生态的常规 package dependency。 |
| user adapter | 生成 runtime 暴露 adapter hook，由应用提供具体 decoder。 |
如何选择
目标支持时，优先用 sora 获得原生 Sora binary bundle。
需要更强可检查性、工具友好性或平台接入简单性时，用 json。
已有 CBOR 依赖，并希望使用通用紧凑二进制 value format 时，用 cbor。
运行环境偏好 Protobuf transport，但仍想保留 Sora 的 schema-driven value model 时，用 sora-protobuf。
CI runtime matrix 会生成此表中每个支持组合，并对轻量可检查的语言做语法检查。
