调研方向
该 issue 未指定文件、测试或入口点；首先定位编译模型元数据和命令方法的处理位置。定义新 info method 暴露的元数据，包括编译详细信息以及可能的 Stan 或 header 内容，然后确定应如何生成编译时 JSON 或其他嵌入式格式，并验证输出支持重新编译和缓存决策。
由索引模型根据 Issue 内容生成。
描述
Summary:
Add a new info method that lets tools (or users) get info about the model to help e.g. deciding if the model needs recompilation.
Description:
Currently, a lot of the metadata about a compiled model can only be retrieved by running inference (Stan version, stanc flags) or not at all (cpp compile options, compiler, ...). This limits the ability of wrappers like cmdstanr to make good decisions on when to recompile a model as a change in compiler options or Stan version will not be recognized by checking modification times.
Beyond choosing to recompile or not, other tools may benefit from this metadata in my own work, the SBC package tries to do caching of its results and needs to check if the model it is given is substantially equivalent to a model the cached results were compiled with. It could rely on modification time, but this could result in some unnecessary recomputations (e.g. when the model is modified, found to be problematic and then the change is reverted). For those more extended usages by tools, it might make sense to also include the Stan code and the contents of user-provided extra .hpp in the information stored.
Since all of the information is known at a compile time, a simple implementation would have a .json (or other format) created at compile time and embedded as a resource. The output format could be configurable, but since the primary consumers are likely to be tools, it should probably default to JSON or similar.
Additional information:
If there is an agreement on implementing this, I'd be happy to write a PR.
