"""
Diagnose für den Graph-Adapter (Subgraph) in mindnet.

Nutzung (aus Projektwurzel):

    (.venv) python tests/diag_subgraph_for_note.py \
        --note-id 20251130-relshow-embeddings-101 \
        --depth 1

Optional:

    --prefix mindnet
    --edge-type references --edge-type related_to ...

Ziel:
    - Ruft app.core.graph_adapter.expand(...) für eine gegebene note_id auf.
    - Gibt edge_bonus und centrality_bonus für diese note_id aus.
    - Zeigt zusätzlich einige Nachbarn und deren Boni.
