Describe the feature

Currently, the ExpressionParser supports $[Outputs('Name').prop] with nested property/array access. However, it does not fully support $[Variables('Name').prop] and recursive expressions where nested $[...] can appear anywhere, including inside the key or inside the access path.

We want to extend the parser to handle any recursive scenario, such as:

$[Outputs(Variables('Config')).details.status]
$[Variables(Outputs('Config')).details.status]
$[Outputs(Outputs(Variables('Deep')).something).foo.bar]
$[Variables(Variables('Var1')).nested[0].value]

Expected Behavior

• Any $[...] inside a key or access path should be recursively evaluated until no unresolved expressions remain.
• Support nested Outputs and Variables in any order.
• Preserve full dynamic nested traversal: .prop[0].nested on objects, JSON strings, arrays.
• Return the final resolved value as a string or object as needed.
• Optionally handle circular references gracefully.
