fix: rename god_nodes 'edges' field to 'degree'

[yangmeilly]

god_nodes() returned a dict with key 'edges' for the degree count, but all consumers (report, serve, wiki, skill scripts) referenced it as 'degree', causing KeyError at runtime.

fix policy

god_nodes() in analyze.py:51-55 returns nodes with the field named "edges", not "degree":

 result.append({
     "id": node_id,
     "label": G.nodes[node_id].get("label", node_id),
     "edges": deg,   # <-- field is "edges", not "degree"
 })

 The "degree" field at export.py:385 belongs to the vis.js node payload and is unrelated to the gods array written to .graphify_analysis.json.

 Fix options:
 1. Rename "edges" → "degree" in analyze.py:54 (preferred — degree is the standard graph theory term)
 2. Update consuming code to use node['edges'] instead of node['degree']
