codex-rs Bazel docs contain stale file references

What happened?

codex-rs/docs/bazel.md contains stale or incorrect Bazel file references:

• It says ../MODULE.bazel defines Bazel dependencies and Rust toolchains, but from codex-rs/docs/ the repo-root file is ../../MODULE.bazel.
• It says ../defs.bzl provides codex_rust_crate, but from codex-rs/docs/ that file is ../../defs.bzl.
• It refers to ../MODULE.bzl for crate.annotation, but there does not appear to be a MODULE.bzl file in the repo; the relevant file is MODULE.bazel.

Expected behavior

The Bazel docs should use valid relative paths from codex-rs/docs/bazel.md and refer to the actual Bazel module file name.

Additional context

I searched open issues and PRs for terms including codex-rs/docs/bazel.md, MODULE.bazel, MODULE.bzl, and defs.bzl, and did not find an existing open item that appears to cover these stale file references.
