Michael Bolin d1e71cd202 feat: add MCP protocol types and rmcp adapters (#10356)
Currently, types from our custom `mcp-types` crate are part of some of
our APIs:


https://github.com/openai/codex/blob/03fcd12e77fedf4fa327af27e2e476e1ebc5f651/codex-rs/app-server-protocol/src/protocol/v2.rs#L43-L46

To eliminate this crate in #10349 by switching to `rmcp`, we need our
own wrappers for the `rmcp` types that we can use in our API, which is
what this PR does.

Note this PR introduces the new API types, but we do not make use of
them until #10349.

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.
