Fix 4 of 8 dead-end nodes in KQVI chart

Fixed:
- O_RECEIVE_BEASTS_RING -.-> END (consumed in Beauty exchange)
- O_RECEIVE_PEARL --> O_RECEIVE_ROYAL_RING (pearl trades for ring)
- O_RECEIVE_SPIDER_WEB --> O_RECEIVE_LOVE_WORD (web contains LOVE word)
- P_PROBLEM_DARK_CAVE --> A_LIGHT_CAVE (problem leads to solution)

Remaining 4 dead-ends are genuinely terminal (informational items or require missing Sing-Sing system)
