Add annotations and an export script that let us generate app-server protocol types as typescript and JSONSchema. The script itself is a bit hacky because we need to manually label some of the types. Unfortunately it seems that enum variants don't get good names by default and end up with something like `EventMsg1`, `EventMsg2`, etc. I'm not an expert in this by any means, but since this is only run manually and we already need to enumerate the types required to describe the protocol, it didn't seem that much worse. An ideal solution here would be to have some kind of root that we could generate schemas for in one go, but I'm not sure if that's compatible with how we generate the protocol today.
codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
