hanzo-dev was a 53-day-frozen diverged fork that release.yml shipped only
because codex-rs's v8 dep was believed to block musl. It doesn't — the prebuilt
rusty_v8 musl artifacts already exist (rust-release.yml uses them). So collapse
to the single canonical tree.
- Delete hanzo-dev/ (1416 paths). codex-rs has zero deps on it; its 'unique'
crates (zap/sse/backoff) aren't needed (codex-rs has its own upstream impls);
zt/zap zero-trust was feature-gated OFF in release builds so it never shipped
(external ~/work/hanzozt SDKs + docs unaffected; design notes kept in LLM.md).
- Repoint every remaining hanzo-dev build/path ref to codex-rs: workflows
(preview-build, issue-code, issue-comment), scripts (ci-tests.sh,
generate-homebrew-formula.sh, pre-release.sh, build-fast.sh, hanzo.sh,
hanzo-cli), code-sign actions, dependabot.yaml, merge-policy.json, docs.
- Port the dev-fast cargo profile into codex-rs/Cargo.toml (build-fast.sh /
pre-release.sh / release.yml preflight all use it).
- Delete obsolete hanzo-dev-only tooling (check-codex-path-deps.sh,
upstream-merge/diff-crates.sh) + repoint their callers.
- package.json/build-fast.sh build only --bin dev (codex-rs has no
dev-tui/dev-exec split bins).
Verified locally: codex-rs builds `dev` (Hanzo Dev header, CODE_VERSION-aware);
zero dangling source refs (only npm package names + Homebrew formula name kept).
This eliminates redundant user documentation and allows us to focus our
documentation investments.
I left tombstone files for most of the existing ".md" docs files to
avoid broken links. These now contain brief links to the developers docs
site.

## Summary
- update documentation, example configs, and automation defaults to
reference gpt-5.1 / gpt-5.1-codex
- bump the CLI and core configuration defaults, model presets, and error
messaging to the new models while keeping the model-family/tool coverage
for legacy slugs
- refresh tests, fixtures, and TUI snapshots so they expect the upgraded
defaults
## Testing
- `cargo test -p codex-core
config::tests::test_precedence_fixture_with_gpt5_profile`

[Codex
Task](https://chatgpt.com/codex/tasks/task_i_6916c5b3c2b08321ace04ee38604fc6b)
This updates `codex exec` so that, by default, most of the agent's
activity is written to stderr so that only the final agent message is
written to stdout. This makes it easier to pipe `codex exec` into
another tool without extra filtering.
I introduced `#![deny(clippy::print_stdout)]` to help enforce this
change and renamed the `ts_println!()` macro to `ts_msg()` because (1)
it no longer calls `println!()` and (2), `ts_eprintln!()` seemed too
long of a name.
While here, this also adds `-o` as an alias for `--output-last-message`.
