Add exec-server stub server and protocol docs (#15089 )

Stacked PR 1/3.

This is the initialize-only exec-server stub slice: binary/client
scaffolding and protocol docs, without exec/filesystem implementation.

refactor: delete exec-server and move execve wrapper into shell-escalation (#12632 )

## Why

We already plan to remove the shell-tool MCP path, and doing that
cleanup first makes the follow-on `shell-escalation` work much simpler.

This change removes the last remaining reason to keep
`codex-rs/exec-server` around by moving the `codex-execve-wrapper`
binary and shared shell test fixtures to the crates/tests that now own
that functionality.

## What Changed

### Delete `codex-rs/exec-server`

- Remove the `exec-server` crate, including the MCP server binary,
MCP-specific modules, and its test support/test suite
- Remove `exec-server` from the `codex-rs` workspace and update
`Cargo.lock`

### Move `codex-execve-wrapper` into `codex-rs/shell-escalation`

- Move the wrapper implementation into `shell-escalation`
(`src/unix/execve_wrapper.rs`)
- Add the `codex-execve-wrapper` binary entrypoint under
`shell-escalation/src/bin/`
- Update `shell-escalation` exports/module layout so the wrapper
entrypoint is hosted there
- Move the wrapper README content from `exec-server` to
`shell-escalation/README.md`

### Move shared shell test fixtures to `app-server`

- Move the DotSlash `bash`/`zsh` test fixtures from
`exec-server/tests/suite/` to `app-server/tests/suite/`
- Update `app-server` zsh-fork tests to reference the new fixture paths

### Keep `shell-tool-mcp` as a shell-assets package

- Update `.github/workflows/shell-tool-mcp.yml` packaging so the npm
artifact contains only patched Bash/Zsh payloads (no Rust binaries)
- Update `shell-tool-mcp/package.json`, `shell-tool-mcp/src/index.ts`,
and docs to reflect the shell-assets-only package shape
- `shell-tool-mcp-ci.yml` does not need changes because it is already
JS-only

## Verification

- `cargo shear`
- `cargo clippy -p codex-shell-escalation --tests`
- `just clippy`

feat(shell-tool-mcp): add patched zsh build pipeline (#11668 )

## Summary
- add `shell-tool-mcp/patches/zsh-exec-wrapper.patch` against upstream
zsh `77045ef899e53b9598bebc5a41db93a548a40ca6`
- add `zsh-linux` and `zsh-darwin` jobs to
`.github/workflows/shell-tool-mcp.yml`
- stage zsh binaries under `artifacts/vendor/<target>/zsh/<variant>/zsh`
- include zsh artifact jobs in `package.needs`
- mark staged zsh binaries executable during packaging

## Notes
- zsh source is cloned from `https://git.code.sf.net/p/zsh/code`
- workflow pins zsh commit `77045ef899e53b9598bebc5a41db93a548a40ca6`
- zsh build runs `./Util/preconfig` before `./configure`

## Validation
- parsed workflow YAML locally (`yaml-ok`)
- validated zsh patch applies cleanly with `git apply --check` on a
fresh zsh clone

docs: update the docs for @openai/codex-shell-tool-mcp (#7962 )

The existing version of `shell-tool-mcp/README.md` was not written in a
way that was meant to be consumed by end-users. This is now fixed.

Added `codex-rs/exec-server/README.md` for the more technical bits.
