cooper-oai c4513cb982 Prevent launch context from reaching child processes (#37607 )

## Why

Model-reachable child processes should not inherit Codex launch context.

## What changed

- Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching.
- Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes.

## Testing

- Cover inherited and explicitly configured variants, including mixed-case names.
- Verify the variables are absent from real child environments and app-server command and process execution.

codex-shell-escalation

This crate contains the Unix shell-escalation protocol implementation and the codex-execve-wrapper executable.

codex-execve-wrapper receives the arguments to an intercepted execve(2) call and delegates the decision to the shell-escalation protocol over a shared file descriptor (specified by the CODEX_ESCALATE_SOCKET environment variable). The server on the other side replies with one of:

Run: codex-execve-wrapper should invoke execve(2) on itself to run the original command within the sandboxed shell.
Escalate: forward the file descriptors of the current process so the command can be run faithfully outside the sandbox. When the process completes, the server forwards the exit code back to codex-execve-wrapper.
Deny: the server has declared the proposed command to be forbidden, so codex-execve-wrapper prints an error to stderr and exits with 1.

Patched zsh

We carry a small patch to Src/exec.c (see patches/zsh-exec-wrapper.patch) that adds support for EXEC_WRAPPER. The patch applies to 77045ef899e53b9598bebc5a41db93a548a40ca6 from https://git.code.sf.net/p/zsh/code. To rebuild manually:

git clone https://git.code.sf.net/p/zsh/code
git checkout 77045ef899e53b9598bebc5a41db93a548a40ca6
git apply /path/to/patches/zsh-exec-wrapper.patch
./Util/preconfig
./configure
make -j"$(nproc)"

Release artifacts are built by .github/workflows/rust-release-zsh.yml when a codex-zsh-vX.Y.Z tag is pushed. When the zsh commit or patch changes, publish the next version tag and update the checked-in DotSlash manifests to use the new release.
