Michael Bolin c7bcb90f9b package: include zsh fork in Codex package (#23756)
## Why

The package layout gives Codex a stable place for runtime helpers that
should travel with the entrypoint. `shell_zsh_fork` still required users
to configure `zsh_path` manually, even though we already publish
prebuilt zsh fork artifacts.

This PR builds on #24129 and uses the shared DotSlash artifact fetcher
to include the zsh fork in Codex packages when a matching target
artifact exists. Packaged Codex builds can then discover the bundled
fork automatically; the user/profile `zsh_path` override is removed so
the feature uses the package-managed artifact instead of a legacy path
knob.

## What Changed

- Added `scripts/codex_package/codex-zsh`, a checked-in DotSlash
manifest for the current macOS arm64 and Linux zsh fork artifacts.
- Taught `scripts/build_codex_package.py` to fetch the matching zsh fork
artifact and install it at `codex-resources/zsh/bin/zsh` when available
for the selected target.
- Added package layout validation for the optional bundled zsh resource.
- Added `InstallContext::bundled_zsh_path()` and
`InstallContext::bundled_zsh_bin_dir()` for package-layout resource
discovery.
- Threaded the packaged zsh path through config loading as the runtime
`zsh_path` for packaged installs, and removed the config/profile/CLI
override path.
- Kept the packaged default zsh override typed as `AbsolutePathBuf`
until the existing runtime `Config::zsh_path` boundary.
- Updated app-server zsh-fork integration tests to spawn
`codex-app-server` from a temporary package layout with
`codex-resources/zsh/bin/zsh`, matching the new packaged discovery path
instead of setting `zsh_path` in config.
- Switched package executable copying from metadata-preserving `copy2()`
to `copyfile()` plus explicit executable bits, which avoids macOS
file-flag failures when local smoke tests use system binaries as inputs.

## Testing

To verify that the `zsh` executable from the Codex package is picked up
correctly, first I ran:

```shell
./scripts/build_codex_package.py
```

which created:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/
```

so then I ran:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/bin/codex exec --enable shell_zsh_fork 'run `echo $0`'
```

which reported the following, as expected:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/codex-resources/zsh/bin/zsh
```
