We don't need that !
We can infere from starting fen string if we are in
a Chess960 game or not. And note that this is a per-position
property, not an application wide one.
A nice trick is to use a custom manipulator (that is an
enum actually) to keep using the handy operator<<() on the
move when sending to std::cout, yes, I have indulged a
bit here ;-)

Rename to move_is_promotion() to be more clear, also add
a new function move_promotion_piece() to get the
promotion piece type in the few places where is needed.
No functional change.

They hide the underlying uniform function call with
no benefit.
A little bit more verbose but now is clear what happens.
No functional change.

It is more clear, at last for me.
Also cleanup evaluate_rook() and evaluate_queen()
No functional change.
