Summary
This PR adds a couple of fixes related to host environment variable access from guest code:
Node's
process.envnow returns the environment map installed by theEnvironmentplugin, which correctly enforces host access configuration and supports loading.envfiles, etc. This fixes #1664, which was not a failure of the env map itself, but instead an issue with formatting when writing to console or usingJSON.stringifyAdditionally, Node
processtests now verify thatenvmatches the map installed by the env plugin instead of checking against host env directly. Tests have been added to verify that theEnvironmentplugin correctly handles host access settings.
