Test/fold multi list issue 190

[aadiexii]

Closes #190

What is the issue?
Issue #190 reported that fold and fold-right should accept a variable number of lists per the SRFI 1 specification.

What was found?
The multi-list support for fold and fold-right has already been implemented in the current codebase (the definitions use rest args . lists and handle both single and multi-list cases). The issue referenced an older commit (43bb071) where this was not yet the case.

What was changed?
Added the canonical SRFI 1 spec examples and additional edge-case tests to
tests/goldfish/liii/list-test.scm:

(fold cons* '() '(a b c) '(1 2 3 4 5)) — SRFI 1 spec example
(fold-right cons* '() '(a b c) '(1 2 3 4 5)) — SRFI 1 spec example
Three-list fold, single-element lists, and empty-list edge cases

Thanks for the second pull request. Well, you need to learn more git skills.

For the second pull request, you should have created a new branch based on the main branch.

Hey @da-liii
Sorry, I created the branch from the wrong base earlier. I’ve opened a clean PR from main now.
