Eric Traut e6a7368810 TUI: split history cells into focused modules (#22704)
## Why

`codex-rs/tui/src/history_cell.rs` had become the dumping ground for
transcript rendering: the shared trait, common helpers, and the concrete
cells for messages, plans, MCP/search, notices, patches, approvals,
session chrome, and separators all lived together. That made small
transcript changes require reopening a very large file and made
ownership less obvious.

## What changed

- Replaced the monolithic `history_cell.rs` with a `history_cell/`
module tree organized by concern.
- Kept the existing `crate::history_cell::*` surface stable through
re-exports in `history_cell/mod.rs`.
- Moved the existing render coverage into `history_cell/tests.rs`.

## Reviewer notes

- This PR is intentionally mechanical in mature — existing code and
tests moving into files that match their concern.
- The snapshot files under `codex-rs/tui/src/history_cell/snapshots/`
moved with the extracted test module. `insta` resolves these unnamed
snapshots relative to the source file that declares them, so this is
path churn only; snapshot contents were not updated.
- The small non-mechanical seam edits are limited to split fallout:
sibling-module visibility for shared cell containers, moving
approval-specific exec-snippet helpers beside approvals, fixing the
separator module path, and keeping a couple of existing test helpers
reachable after extraction.

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Install globally with your preferred package manager:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
