## Why
The Codex package builder should produce a complete package without
requiring callers to pre-populate `rg` under `codex-cli/vendor` or have
`dotslash` installed on `PATH`. The repo already tracks the
authoritative DotSlash manifest in `codex-cli/bin/rg`, so the builder
can read that metadata directly and fetch the correct ripgrep archive
for the target it is packaging.
## What changed
- Added `scripts/codex_package/ripgrep.py` to parse `codex-cli/bin/rg`
after stripping the shebang, select the target platform entry, download
the configured artifact, and verify the recorded size and SHA-256
digest.
- Added a cache under `$TMPDIR/codex-package/<target>-rg` so verified
archives can be reused without fetching again.
- Extracted `rg`/`rg.exe` from `tar.gz` and `zip` artifacts into the
package-builder cache, then copied that into `codex-path` through the
existing package layout flow.
- Kept `--rg-bin` as an explicit local override for offline tests and
unusual local workflows.
- Documented the default `rg` fetch/cache behavior in
`scripts/codex_package/README.md`.
## Verification
- Ran wrapper/module syntax compilation.
- Ran `scripts/build_codex_package.py --help` from `/private/tmp`.
- Ran a local manifest fetch test covering shebang-stripped manifest
parsing, `tar.gz` extraction, `zip` extraction, size/SHA-256
verification, and cache reuse after deleting the original source
archives.
- Ran fake-cargo package/archive builds for macOS, Linux, and Windows
target layouts with `--rg-bin`, including an assertion that generated
tar archives contain no duplicate member names.

## Why
Codex CLI packaging is currently split across npm staging, standalone
installers, and release bundle creation, which makes it hard to define
and validate a single valid package directory. This adds the first
standalone package builder so later release paths can converge on the
same canonical layout.
## What changed
- Added `scripts/build_codex_package.py` as the stable executable
wrapper around `scripts/codex_package`.
- Added modules for CLI parsing, target metadata, grouped cargo builds,
package layout validation, and archive writing.
- The builder creates a package directory with `codex-package.json`,
`bin/`, `codex-resources/`, and `codex-path`, and can serialize it as
`.tar.gz`, `.tar.zst`, or `.zip`.
- Source-built artifacts are built by one grouped `cargo build`: `codex`
for all targets, `bwrap` for Linux, and the Windows sandbox helpers for
Windows. `rg` remains an input because it is vendored from upstream
rather than built from this repo.
- Added `scripts/codex_package/README.md` to document the package
layout, source-built artifacts, and cargo profile behavior.
## Verification
- Ran wrapper/module syntax compilation.
- Ran `scripts/build_codex_package.py --help` from `/private/tmp`.
- Ran fake-cargo package/archive builds for macOS, Linux, and Windows
target layouts, including an assertion that generated tar archives
contain no duplicate member names.
