aidan 7d3e696c4c Preserve Windows environment variables for remote MCP servers (#50129) ...

## Why

When Codex runs on Unix and launches a stdio MCP server on a Windows executor, explicit remote environment variables activate an allowlist based on Unix defaults. This can filter out Windows runtime and temporary-directory variables.

## What changed

Include `SYSTEMROOT`, `TEMP`, and `TMP` in the remote environment allowlist whenever explicit remote variables are requested.

## Testing

Extend the environment-filtering test to verify that `SystemRoot`, `TEMP`, and `TMP` survive alongside requested variables while unrequested secrets remain excluded.
