pub fn extract_include_entries(v: &Value) -> Vec<IncludeEntry>Expand description
Parse the top-level include: value into a flat list of IncludeEntrys.
include: accepts five shapes — string, sequence-of-strings, sequence-of-mappings,
sequence-of-strings-mixed-with-mappings, and a single mapping. Normalise all of
them into one flat list so the rule layer doesn’t have to.
