fix: allow anchor moves to reach exit with key

Browse Source 
Update findAnchorTarget to accept optional hasKey parameter. When player has the key and moving to an anchor (gg, G, ^, or $), if an exit is positioned at the edge, allow movement to reach it. This matches behavior of counted moves like 5k that can reach edge-positioned exits.
