Michael Bolin 31d0d7a305 feat: initial import of Rust implementation of Codex CLI in codex-rs/ (#629 )

As stated in `codex-rs/README.md`:

Today, Codex CLI is written in TypeScript and requires Node.js 22+ to
run it. For a number of users, this runtime requirement inhibits
adoption: they would be better served by a standalone executable. As
maintainers, we want Codex to run efficiently in a wide range of
environments with minimal overhead. We also want to take advantage of
operating system-specific APIs to provide better sandboxing, where
possible.

To that end, we are moving forward with a Rust implementation of Codex
CLI contained in this folder, which has the following benefits:

- The CLI compiles to small, standalone, platform-specific binaries.
- Can make direct, native calls to
[seccomp](https://man7.org/linux/man-pages/man2/seccomp.2.html) and
[landlock](https://man7.org/linux/man-pages/man7/landlock.7.html) in
order to support sandboxing on Linux.
- No runtime garbage collection, resulting in lower memory consumption
and better, more predictable performance.

Currently, the Rust implementation is materially behind the TypeScript
implementation in functionality, so continue to use the TypeScript
implmentation for the time being. We will publish native executables via
GitHub Releases as soon as we feel the Rust version is usable.

Small helper functions that wrap functionality from https://crates.io/crates/ansi-to-tui:

pub fn ansi_escape_line(s: &str) -> Line<'static>
pub fn ansi_escape<'a>(s: &'a str) -> Text<'a>

Advantages:

ansi_to_tui::IntoText is not in scope for the entire TUI crate
we panic!() and log if IntoText returns an Err and log it so that the caller does not have to deal with it
