This updates the MCP server so that if it receives an `ExecApprovalRequest` from the `Codex` session, it in turn sends an [MCP elicitation](https://modelcontextprotocol.io/specification/draft/client/elicitation) to the client to ask for the approval decision. Upon getting a response, it forwards the client's decision via `Op::ExecApproval`. Admittedly, we should be doing the same thing for `ApplyPatchApprovalRequest`, but this is our first time experimenting with elicitations, so I'm inclined to defer wiring that code path up until we feel good about how this one works. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Though for non-Rust UIs, we are also working to define a protocol for talking to Codex. See:
You can use the proto subcommand using the executable in the cli crate to speak the protocol using newline-delimited-JSON over stdin/stdout.
