Adam Perry @ OpenAI 4c79527e31 core: render remote environment cwd natively (#28152 )

## Why

Model-visible `<environment_context>` should match the environment of
the executor, not of the app server.

Stacked on #28146.

## What

- Keep selected environment cwd values as `PathUri` while building
environment context.
- Render cwd text using the path convention represented by the URI, with
the canonical URI as a fallback.
- Preserve compatibility with legacy `TurnContextItem.cwd` values when
reconstructing and diffing context.
- Extend the Wine-backed remote Windows test to assert that the model
sees `powershell` and `C:\windows`.

Windows remote-environment test

This Bazel-only test_codex integration test runs a Windows exec-server fixture under pinned Wine and exercises the normal model tool-call and remote-execution path.

Running the test

bazel test \
  //codex-rs/core/tests/remote_env_windows:smoke-test \
  --test_output=errors

No system Wine is required. Every process gets a fresh WINEPREFIX and isolated wineserver.

Current limitations

ConPTY/TTY behavior is not yet covered.
Wine loads shared objects and PE DLLs at runtime, so the host must still provide the declared compatible glibc version.
The target is intentionally limited to x86-64 for simplicity. It can expand if we find aarch64-specific behavior worth testing.
