Eric Traut 2630a6ca35 Refactor chatwidget input flow into modules (#22407)
## Why

`chatwidget.rs` is still carrying too many unrelated responsibilities in
one file. #22269 started a five-phase effort to move coherent behavior
domains into focused modules while keeping `chatwidget.rs` as the
composition layer.

This PR is phase 2 of that plan. It extracts the input and submission
flow as a mechanical move before the later protocol, popup/status, and
constructor/orchestration phases.

## What Changed

- Added `codex-rs/tui/src/chatwidget/input_flow.rs` for composer input
results, queued user-message draining, pending-input previews, and
mode-specific submission entry points.
- Added `codex-rs/tui/src/chatwidget/input_submission.rs` for
user-message construction/submission, shell prompt submission,
structured mention resolution, and blocked image draft restoration.
- Added `codex-rs/tui/src/chatwidget/input_restore.rs` for
initial-message submission, pending steer restoration after interrupts,
and thread input snapshot/restore behavior.
- Registered the new modules and removed the moved `ChatWidget` impl
methods from `codex-rs/tui/src/chatwidget.rs`.

## Follow-On Refactor Phases

The five-phase plan from #22269 is:

- Phase 1: mechanical helper and state moves. Completed in #22269.
- Phase 2: extract input and submission flow, including queued user
messages, shell prompt submission, pending steer restoration, and thread
input snapshot/restore behavior. This PR.
- Phase 3: extract protocol, replay, streaming, and tool lifecycle
handling, while preserving active-cell grouping, transcript
invalidation, interrupt deferral, and final-message separator behavior.
- Phase 4: extract settings, popups, and status surfaces, including
model/reasoning/collaboration/personality popups, permission prompts,
rate-limit UI, and connectors helpers.
- Phase 5: clean up the remaining constructor and orchestration code
once the larger behavior domains have moved out, leaving `chatwidget.rs`
as the composition layer.

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.
