Michael Bolin 343a74076f build: package prebuilt Codex entrypoints (#23586)
## Why

The package builder should describe the binaries it is actually
packaging, not require callers to restate release metadata out of band.
A caller-provided `--version` flag can drift from the workspace version,
but running the target entrypoint to discover its version breaks
cross-target packages when the produced binary cannot execute on the
build host.

This PR keeps package metadata tied to the repository source of truth by
reading `[workspace.package].version` from `codex-rs/Cargo.toml`. It
also prepares the package layout for `codex-app-server` packages: the
same package structure can now represent either the CLI entrypoint or
the app-server entrypoint while keeping shared sidecars such as `rg`,
`bwrap`, and Windows sandbox helpers in the existing package
directories.

## What changed

- Removes the `--version` CLI flag from
`scripts/build_codex_package.py`.
- Adds Cargo.toml version discovery for `codex-package.json.version` via
`codex-rs/Cargo.toml`.
- Adds `--entrypoint-bin` so callers can package a prebuilt entrypoint
instead of rebuilding it with Cargo.
- Makes `--variant` an explicit choice between `codex` and
`codex-app-server`, and uses it to select the cargo binary and packaged
`bin/` entrypoint name.
- Updates `scripts/codex_package/README.md` to document variants,
prebuilt entrypoints, and Cargo.toml version detection.

## Verification

- Compiled `scripts/build_codex_package.py` and
`scripts/codex_package/*.py` with `PYTHONDONTWRITEBYTECODE=1`.
- Ran `scripts/build_codex_package.py --help` and verified `--version`
is gone while `--variant` and `--entrypoint-bin` are present.
- Verified the package builder reads version `0.0.0` from
`codex-rs/Cargo.toml`.
- Built a fake cross-target `codex-app-server` package using a
non-executable `--entrypoint-bin`; verified metadata records version
`0.0.0`, variant `codex-app-server`, and `bin/codex-app-server` as the
entrypoint.
