Tracker::IndirectImagePlan lives in an anonymous namespace, so std::projected
cannot be formed for it and the three std::ranges algorithms over
m_indirect_images fail to compile under clang-cl with the MSVC STL:
error: function 'std::projected<..., std::identity>::operator*' is used but
not defined in this translation unit, and cannot be defined in any other
translation unit because its type does not have linkage
Using the iterator-pair overloads compiles and is otherwise identical.
Seen with clang-cl and MSVC 14.29 (VS2019) STL. CI does not catch this because
its build targets are launcher and the smaller test binaries; kyty_emulator,
which is what pulls in this file, is never built there.
