Fixed critical issues:
- P_PROBLEM_JOLLO_ROOM: Changed dashed to solid edge from O_RECEIVE_JOLLO_TRUST
- A_SHOW_LETTER: Changed dashed to solid edge from O_RECEIVE_VIZIER_LETTER
- A_CASSIMA_FIGHTS: Changed dashed to solid edge from O_CASSIMA_ARMED
- A_TRADE_COAL_FOR_EGG: Defined as node (was referenced but never defined)
- O_RECEIVE_SULFUR_EGG: Added outcome node and connected to P_PROBLEM_SPELL_COMPONENTS
- O_PASSWORD_ALI/ZEBU: Split multi-source edge for proper script parsing
- O_TREASURY_OPEN: Connected to P_PROBLEM_GENIE for good ending flow
Remaining 46 dead-ends are multi-source edge parsing artifacts where the
script doesn't recognize parallel items converging via multi-source syntax.
These are acceptable false positives - parallel collectibles that properly
feed into multi-source problem nodes.
