Module review 

Functions

print_review_envelope

print_review_envelope_from_codeclimate_issues

render_review_envelope

render_review_envelope_with_diff

Render path the print site uses. Exposed so unit tests can pass a hand-crafted DiffIndex without poking the process-wide SHARED_DIFF cache (which is OnceLock-bounded and not reentrant under cargo test’s parallel runner).
