Environment-dump redaction can be skipped by callers, though it still redacts by default.

What

The helper that strips bearer tokens and credentials before environment variables are logged now takes a mode argument and returns the values untouched when a caller passes "none". The default is still to redact everything.

Evidence

if (e === "none") return r;

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
