Add option for ExportCSVConfig to target txn outputs#262

builtin.tuple is registered as variadic (arity -1), so make_builtin
gives it an empty param list and the generic type-variable matching
can't resolve the return type T. Add a special case that infers
TupleType directly from the argument types, matching what _infer_type
already does in the parser.
Without this, IfElse nodes wrapping tuple constructs were typed as
interface{} in Go, causing a compile error when the function's declared
return type is []interface{}.

…xportCSVConfig ExportCSVColumns had no custom == so structural comparison fell back to identity, breaking ExportCSVSource comparisons. Add equality for ExportCSVColumns first, then ExportCSVSource, then wire csv_source, csv_config, and the new transaction_output_name field into ExportCSVConfig ==, hash, and isequal.

There was a problem hiding this comment.
The new grammar rule i think is the first use of tuples as return values in the grammar, and this exposed a bug in the parser generator. I'm not super sure on the details, but Claude found the problem and this was its fix

This PR adds a new option
transaction_output_nametoExportCSVConfig. This option is used to specify that a CSV export result should be returned by the engine as part of transaction results, rather than written to a client-controlled path.
