SkillId.h: the full SKID table (1929 entries) from skillinfoz/skillid.lua. SkillInfo.cpp: every numeric skill ID replaced by its SkillId name; Sub773A00/Sub773CB0/Sub773CD0/Sub7745B0/CSkillActionMgr::Sub77B4A0 renamed IsOptionalSelfTargetSkill/HidesUseFailureMessage/IsSupportSkill/ShowsCastEffect/CSkillActionMgr::IsSupportAction from their call sites; CSkillInfo::operator= copies scalars by assignment instead of memcpy. Compiled code unchanged (all includers checked).
