This PR does two things because after I got deep into the first one I started pulling on the thread to the second: - Makes `ConversationManager` the place where all in-memory conversations are created and stored. Previously, `MessageProcessor` in the `codex-mcp-server` crate was doing this via its `session_map`, but this is something that should be done in `codex-core`. - It unwinds the `ctrl_c: tokio::sync::Notify` that was threaded throughout our code. I think this made sense at one time, but now that we handle Ctrl-C within the TUI and have a proper `Op::Interrupt` event, I don't think this was quite right, so I removed it. For `codex exec` and `codex proto`, we now use `tokio::signal::ctrl_c()` directly, but we no longer make `Notify` a field of `Codex` or `CodexConversation`. Changes of note: - Adds the files `conversation_manager.rs` and `codex_conversation.rs` to `codex-core`. - `Codex` and `CodexSpawnOk` are no longer exported from `codex-core`: other crates must use `CodexConversation` instead (which is created via `ConversationManager`). - `core/src/codex_wrapper.rs` has been deleted in favor of `ConversationManager`. - `ConversationManager::new_conversation()` returns `NewConversation`, which is in line with the `new_conversation` tool we want to add to the MCP server. Note `NewConversation` includes `SessionConfiguredEvent`, so we eliminate checks in cases like `codex-rs/core/tests/client.rs` to verify `SessionConfiguredEvent` is the first event because that is now internal to `ConversationManager`. - Quite a bit of code was deleted from `codex-rs/mcp-server/src/message_processor.rs` since it no longer has to manage multiple conversations itself: it goes through `ConversationManager` instead. - `core/tests/live_agent.rs` has been deleted because I had to update a bunch of tests and all the tests in here were ignored, and I don't think anyone ever ran them, so this was just technical debt, at this point. - Removed `notify_on_sigint()` from `util.rs` (and in a follow-up, I hope to refactor the blandly-named `util.rs` into more descriptive files). - In general, I started replacing local variables named `codex` as `conversation`, where appropriate, though admittedly I didn't do it through all the integration tests because that would have added a lot of noise to this PR. --- [//]: # (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.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this
macOS
Expects /usr/bin/sandbox-exec to be present.
Linux
Expects the binary containing codex-core to run the equivalent of codex debug landlock when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
