fix: also exclude .env from default profile exports

The original PR excluded auth.json from _DEFAULT_EXPORT_EXCLUDE_ROOT and
filtered both auth.json and .env from named profile exports, but missed
adding .env to the default profile exclusion set. Default exports would
still leak .env containing API keys.

Added .env to _DEFAULT_EXPORT_EXCLUDE_ROOT, added test coverage, and
updated the existing test that incorrectly asserted .env presence.
