jif c30a3e49c9 Support sandboxed file streaming in exec-server (#38356)
## Why

Streaming reads previously rejected requests that used a platform filesystem
sandbox.

## What changed

- Open streamed files in the sandbox helper and return the open file to the
  exec-server by passing a file descriptor on Unix or duplicating a file handle
  on Windows.
- Advertise support through the `sandboxedFileStreaming` environment capability.
- Preserve close-on-exec behavior for transferred descriptors, including the
  required inherited-descriptor cleanup on macOS.

## Testing

- Cover bounded sandboxed streams, continued reads after path replacement, and
  rejection of symlink escapes outside readable roots.

starr-openaiandCodex d626dc3895 Run exec-server fs operations through sandbox helper (#17294)
## Summary
- run exec-server filesystem RPCs requiring sandboxing through a
`codex-fs` arg0 helper over stdin/stdout
- keep direct local filesystem execution for `DangerFullAccess` and
external sandbox policies
- remove the standalone exec-server binary path in favor of top-level
arg0 dispatch/runtime paths
- add sandbox escape regression coverage for local and remote filesystem
paths

## Validation
- `just fmt`
- `git diff --check`
- remote devbox: `cd codex-rs && bazel test --bes_backend=
--bes_results_url= //codex-rs/exec-server:all` (6/6 passed)
