Refactor step 6. MessageLine (was MsgLine) owns the msg/addmsg/endmsg machinery, wired to its screen, pre---More-- redraw, and input via attach(); RogueGame keeps one-line msg/addmsgf/endmsg shorthands so the ~400 call sites are unchanged. Player gains nextPackChar and removeFromPack (the state half of pack.c leave_pack); leavePack keeps only the LastPick repeat-command tracking. Level gains ObjectAt (misc.c find_obj) and AddObject/RemoveObject/AddMonster/RemoveMonster, replacing direct attach/detach calls on the level lists. Inventory and pickup UI flows stay on RogueGame: display and orchestration, not state surgery. Behavior and RNG order unchanged; suite green.
