Function string_keyed_to_eval 

pub fn string_keyed_to_eval(sk: &StringKeyedValue) -> Value

Convert a StringKeyedValue (from the bytecode VM) to a tree-walker Value.

This is the primary conversion path: the VM evaluates an expression and returns a StringKeyedValue (fully resolved string keys), which we then convert to the Value type used by the rest of sui (build, orchestrate, etc.).
