Add IW4 pointer-walk reader & editor bridge

Introduce support for the IW4 (MW2 PS3) pointer-following zone reader and bridge it into the editor. Adds a new FastFileLib.Iw4 reader set (Iw4ZoneReader, ZonePointer, Memory, readers, models, etc.) and unit tests for the reader/pointer model. Implements Iw4AssetBridge to map IW4-parsed assets (rawfiles, localize, stringtables, weapons, techsets, menus) into the editor models and prefer the IW4 walk for MW2 PS3 zones when complete. UI changes: new AssetSelectionDialog toggles (stringtables, weapons, images, techsets), integrate loading flags in MainWindow, and add WeaponDetailForm to show read-only structured IW4 weapons (WeaponAsset updated with IsStructuredView/DetailFields). Minor fixes: MW2 game definition techset recognition and a clarification comment in Cod5MenuDeserializer about pointer heuristics.
