gtopt/sddp_common.hpp file

Common types and forward declarations for the SDDP subsystem.

Lightweight header with SDDP-specific strong types, forward declarations, and small structures shared by sddp_solver, sddp_aperture, sddp_cut_io, and sddp_monitor. This avoids circular includes: consumers that only need the basic types include this file instead of sddp_method.hpp.
