The integration tests that shipped with #1158 use inputs too small to trigger
the tree-sitter class_specifier collapse, so they pass with OR without the fix
(verified: 0/3 reproduce on the pre-fix build) — only the offset-preserving unit
tests actually guard the behavior. This adds a real guard: a ~240-in-body-macro
reflected class (the density of the real CharacterMovementComponent.h) plus a
UENUM whose values carry mid-line UMETA. Asserting the decorated members and the
enum are extracted flips false->true across the three blank passes — verified the
same assertions FAIL on the pre-fix source (2a06d9a) and PASS on the fix.
The full class collapse is emergent from real engine-header content that can't be
shipped (Unreal source is EULA-licensed); this reproduces the recoverable-member
signal the collapse leaves, which regresses if any of blankCppAnnotationMacroCalls
/ blankCppApiPrefixMacros / blankCppInlineAnnotationMacros is reverted.
