Add RCO object model and expose the menu object tree

- Type system: BaseType (+Int/Float/Unknown) and BaseReferenceType
  (+Event/Image/Text/Ref/Object/Model) for typed record fields.
- Object model: BaseObject/BasePositionObject and all 25 object classes
  (Page, Plane, Button, UButton, Text, Model, Icon, Group, Action,
  XMenu/XMList/XList/XItem, MList/MItem, LList/LItem, IList/IItem,
  Progress, Scroll, Spin, ItemSpin, Edit, Clock) with reflection-based
  field deserialization.
- ObjectFactory + RcoContext materialize 89 objects and 81 images from
  the RCO; RcoFile resolves references and wires entry.obj/vsmxObject.
- Resource builds the live pagetable/animtable/soundtable/texturetable
  into the VSMX tree; Controller tracks input focus.
- Validated on Batman Begins: onAutoPlay still drives playback
  (stream 00003) with the object tree populated.
