Alexander Smirnov 183fc8e01a core: replace Cloudflare 403 HTML with friendly message (#6252 )

### Motivation

When Codex is launched from a region where Cloudflare blocks access (for
example, Russia), the CLI currently dumps Cloudflare’s entire HTML error
page. This isn’t actionable and makes it hard for users to understand
what happened. We want to detect the Cloudflare block and show a
concise, user-friendly explanation instead.

### What Changed

- Added CLOUDFLARE_BLOCKED_MESSAGE and a friendly_message() helper to
UnexpectedResponseError. Whenever we see a 403 whose body contains the
Cloudflare block notice, we now emit a single-line message (Access
blocked by Cloudflare…) while preserving the HTTP status and request id.
All other responses keep the original behaviour.
- Added two focused unit tests:
- unexpected_status_cloudflare_html_is_simplified ensures the Cloudflare
HTML case yields the friendly message.
- unexpected_status_non_html_is_unchanged confirms plain-text 403s still
return the raw body.

### Testing

- cargo build -p codex-cli
- cargo test -p codex-core
- just fix -p codex-core
- cargo test --all-features

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 support matrix is:

macOS

Expects /usr/bin/sandbox-exec to be present.

Linux

Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: 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.
