fix(client): resolve GDScript autoload parse-order errors

Autoload scripts are parsed before regular scripts, so class_name
types (CharacterVisualDescriptor, TestHarness, YamlParser) are not
available at parse time. Replace type annotations with untyped vars
and use load() for in-body class references. Fixes all 14 headless
parse errors (9 pre-existing + 5 from Sprint 30 changes).
