-Zweck
------
-- Liest Markdown-Notizen aus einem Vault ein
-- Erzeugt Note-Payload, Chunk-Payloads (+ optionale Embeddings) und Edges
-- Schreibt alles idempotent in Qdrant (Notes, Chunks, Edges)
-- Integriert eine optionale Type-Registry (types.yaml), um z. B. chunk_profile
-  und retriever_weight pro Notiz-Typ zu steuern.
-
-Wesentliche Fixes ggü. vorherigen fehlerhaften Ständen
-------------------------------------------------------
-- `embed_texts` wird optional importiert und defensiv geprüft (kein NameError mehr)
-- `effective_chunk_profile` / `effective_retriever_weight` und Registry-Helfer
-  sind VOR `main()` definiert (kein NameError mehr)
-- `retriever_weight` wird in Note- und Chunk-Payload zuverlässig gesetzt
-- Robuste Kantenbildung; Fehler bei Edges blockieren Notes/Chunks nicht
-- Korrekte Verwendung von `scroll_filter` beim Qdrant-Client
-- `--purge-before-upsert` entfernt alte Chunks/Edges einer Note vor dem Upsert
-
-Qdrant / ENV
-------------
-- QDRANT_URL | QDRANT_HOST/QDRANT_PORT | QDRANT_API_KEY
-- COLLECTION_PREFIX (Default: mindnet), via --prefix überschreibbar
-- VECTOR_DIM (Default: 384)
-- MINDNET_NOTE_SCOPE_REFS: true|false (Default: false)
-- MINDNET_TYPES_FILE: Pfad zu types.yaml (optional; Default: ./types.yaml)
