audio_hook.cpp carried its own VtableHook class identical to the shared
hook/src/vtable_hook.hpp -- two copies of the same delicate vtable-swap unhook
logic to keep in sync. Drop the audio copy and use the shared one (it's in
namespace coop::hook, so the in-file references resolve to it), leaving a short
note on why WASAPI methods are vtable-swapped rather than inline-hooked. Update
the shared header's comment to name both users (audio + DirectInput).
Last item from the review pass -- the Roadmap's Current-work section is now empty
(done work lives in git history); only Future work remains. Validated by
audio_hook_test (the vtable swap still hooks GetService/GetBuffer/ReleaseBuffer
end to end).
