This updates the schema in `generate_mcp_types.py` from `2025-03-26` to `2025-06-18`, regenerates `mcp-types/src/lib.rs`, and then updates all the code that uses `mcp-types` to honor the changes. Ran ``` npx @modelcontextprotocol/inspector just codex mcp ``` and verified that I was able to invoke the `codex` tool, as expected. --- [//]: # (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.
