Extract duplicated WoW 1.12.1 addresses and game accessor functions into shared modules (src/offsets.zig, src/wow.zig), replacing 5+ copies of getObjectByGUID, isInBattleground, isValidPtr, etc. - src/offsets.zig: shared address constants (object manager, descriptor fields, map/zone, core function addresses, D3D9/GX) - src/wow.zig: shared accessor functions (pointer validation, object manager traversal, field reads, unit helpers, battleground detection, game function wrappers, raid target cache) - Update 10 modules to import from shared instead of inline constants - Remove outline/wow.zig (promoted to src/wow.zig) - Trim outline/offsets.zig and markers/offsets.zig to module-specific only
