Reworked resubmission of #744 and #714 after review, keeping only the ops the reviewer called correct and current. DRLGGRID_OrFlagOnCellList 0014e1ee compares against [arg+8]/[arg+0xc] and dereferences [arg], matching D2DrlgGridStrc (Windows twin #737 applied). CLIENT_StoreUnitGuidForQuestTracking 0007f92a null-tests its argument and reads [arg+0xc] nUnitGUID. The stale UNITS_CheckSkillTargetAlignment op is dropped. The rename nGridPtr -> pGrid the reviewer wants is refused by the checker (chosen name) and goes in the separate GitHub issue.
