Cursor wasn't moving when inserting a file, resulting in being not at
the end of the filename when inserting the file.
This fixes it by moving the cursor to the end of the file + one trailing
space.

This sets up the scaffolding and basic flow for a TUI onboarding
experience. It covers sign in with ChatGPT, env auth, as well as some
safety guidance.
Next up:
1. Replace the git warning screen
2. Use this to configure default approval/sandbox modes
Note the shimmer flashes are from me slicing the video, not jank.

## Summary
We have been returning `exit code 0` from the apply patch command when
writes fail, which causes our `exec` harness to pass back confusing
messages to the model. Instead, we should loudly fail so that the
harness and the model can handle these errors appropriately.
Also adds a test to confirm this behavior.
## Testing
- `cargo test -p codex-apply-patch`
- Arguably a bugfix as previously CTRL-Z didn't do anything.
- Only in TUI mode for now. This may make sense in other modes... to be
researched.
- The TUI runs the terminal in raw mode and the signals arrive as key
events, so we handle CTRL-Z as a key event just like CTRL-C.
- Not adding UI for it as a composer redesign is coming, and we can just
add it then.
- We should follow with CTRL-Z a second time doing the native terminal
action.
- Updates the launch screen to:
```
>_ You are using OpenAI Codex in ~/code/codex/codex-rs
Try one of the following commands to get started:
1. /init - Create an AGENTS.md file with instructions for Codex
2. /status - Show current session configuration and token usage
3. /compact - Compact the chat history
4. /new - Start a new chat
```
- These aren't the perfect commands, but as more land soon we can
update.
- We should also add logic later to make /init only show when there's no
existing AGENTS.md.
- Majorly need to iterate on copy.

## Summary
- Prioritize provider-specific API keys over default Codex auth when
building requests
- Add test to ensure provider env var auth overrides default auth
## Testing
- `just fmt`
- `just fix` *(fails: `let` expressions in this position are unstable)*
- `cargo test --all-features` *(fails: `let` expressions in this
position are unstable)*
