Reorder subgraphs to follow game progression, eliminating upward edges

The graph now follows the natural game flow:
Crown (Start) → Wonder → Beast → Mists → Dead → Crown (Final) → END

This eliminates the long upward edge from O_JOLLO_HELPS (originating in Beast Return) to the Castle Final area.

Also adds back O_RECEIVE_COAL_IOM --> A_TRADE_COAL_FOR_EGG connection.

Updates skill documentation with subgraph ordering guidance.

 - **When to split**: If lines would stretch more than ~15 nodes vertically, create a new subgraph
 - **Trade-off**: More subgraphs with fewer nodes each is better than few subgraphs with long chains
 
+**Subgraph Ordering (CRITICAL)**:
+- **Order subgraphs to follow game progression**: Place subgraphs in the order the player encounters them
+- **Avoid upward edges**: If a node in subgraph A is used by a node in subgraph B, and B appears AFTER A in the game, subgraph B should come AFTER subgraph A in the file
+- **Eliminate backward dependencies**: Reorder subgraphs so edges flow downward (top-to-bottom), never upward
+- **Example of WRONG order**: If "Isle of Beast Return" (where Jollo's help originates) is placed AFTER "Isle of Crown Final" (where Jollo's help is used), edges must travel upward - this creates long confusing lines
+- **Correct order**: Crown → Wonder → Beast → Mists → Dead → Crown Final (matches game flow)
