Only handles DeclRefExpr and single-arg CXXConstructExpr wrapping a
DeclRefExpr. Misses common cases:
```
auto [a, b] = make_point(); // CallExpr
auto [a, b] = Point{1, 2}; // InitListExpr / BraceInit
auto [a, b] = std::move(p); // CXXStdInitializerList / cast chain
```
When getOriginalVar() returns nullptr, MapBaseChecker falls back to mapping the
DecompositionDecl itself. That may produce redundant or incorrect target maps
compared to mapping the underlying object. Do we diagnose such cases?
