how I might manage pointers that get turned into `nil` in an array of pointers from C++

That. Don't do that. Use something other than Lua `nil` to represent C++ NULL. If you want something unique, then

NULL = {}

is a good choice. NULL won't create a hole in a sequence.

NULL represents a pointer to nothing.

nil is nothing itself.
