* fix(workflows): preserve commas inside quoted list-literal elements
The simple-expression evaluator parsed a list literal with a naive
`inner.split(",")`, which splits on commas inside quoted strings (and
nested brackets). So `{{ ["a, b", "c"] }}` evaluated to three items
(`["a", "b", "c"]`) instead of two, silently corrupting `fan-out` `items:`
and any list expression that contains a comma inside a quoted element.
Split list-literal elements on top-level commas only, ignoring commas
inside quotes or nested brackets, via a small `_split_top_level_commas`
helper. Plain and empty lists are unchanged.
Add tests covering quoted commas, nested lists, and the existing
plain/empty cases.

* test(workflows): cover single-quoted and nested list literals
Address review: extend the list-literal regression test to assert single-quoted elements with commas and nested lists parse correctly, alongside the existing double-quoted cases.
