refactor(json): convert JsonEncode to idiomatic FFI

[akonwi]

Summary

Converts JsonEncode from raw FFI to idiomatic FFI.

Changes

Before:

func JsonEncode(args []*runtime.Object) *runtime.Object

After:

func JsonEncode(value any) (string, error)

Generated Wrapper

func _ffi_JsonEncode(args []*runtime.Object) *runtime.Object {
    arg0 := args[0].Raw()
    result, err := ffi.JsonEncode(arg0)
    if err != nil {
        return runtime.MakeErr(runtime.MakeStr(err.Error()))
    }
    return runtime.MakeOk(runtime.MakeStr(result))
}

Cleanup

• Removed runtime import from json.go

Stats

• Raw FFI: 10 → 9
• Idiomatic FFI: 63 → 64
