fix(cli): logs entire environment

[rix0rrr]

Right now the CLI logs the entire environment to debug logging. This is a lot of data, and potentially also includes tokens we'd rather don't end up in logging.

Instead, just log our additions to the existing environment.

Any chance we can make this change in a way that the next person working on this code doesn't see the double env assignment and "optimizes" it away? Thus creating a regression?

A test case would help. Or variable naming maybe or moving process.env into the writeContextToEnv helper.

I did both.
