Engine-surface extractor for Piklib/BlooMoo + golden-pair snapshots

Ghidra headless post-script (pyghidra/Jython) that extracts the scripting
"surface" of Aidem Media engine DLLs into a versionable snapshot.json, for
diffing engine versions. All four axes validated on the golden pair
(PIKLIB8.dll / MSVC6 vs bloomoodll.dll / MSVC8):

- types   : CMC_ObjectsContainer::resolve factory ladder
            (script name -> C++ class, ctor, object size; + dispatch_addr,
            via_module_iface for the dual MULTIARRAY branch)
- methods : CMC_*_Runner::prepareMthHashSet (name -> id) + inheritance chain
- events  : CMC_*::getBehavioursList (ordered per-class list)
- fields  : CMC_* ctor -> CMElement::getProperty<T>Value (name + type)
            (+ bonus struct_layout: this+offset stores via decompiler P-code)

Extraction rests on semantic anchors (call targets, referenced string
literals, push/immediate operands), never decompiled-C text, so the same
script works across both compilers despite ILT stubs, undefined string
literals, unnamed FUN_ ctors and an MSVC6 inline-strcpy off-by-one.
