-Script: scripts/import_markdown.py — Markdown → Qdrant (Notes, Chunks, Edges)
-Version: 3.7.1
-Datum: 2025-09-30
-
-Kurzbeschreibung
-----------------
-- Liest Markdown-Dateien ein und erzeugt Notes/Chunks/Edges **idempotent**.
-- Robuste Änderungserkennung (Option C): Mehrfach-Hashes werden parallel in der Note
-  gespeichert (Feld `hashes` mit Schlüsseln `<mode>:<source>:<normalize>`). Der Vergleich
-  erfolgt **modusgenau** anhand dieses Keys, sodass ein Wechsel des Vergleichsmodus **keine
-  Massenänderungen** mehr triggert.
-- **Erstimport-Fix:** Bei leerem Qdrant gilt Create-Fall automatisch als geändert.
-- **--baseline-modes:** fehlende Hash-Varianten „still“ nachtragen (nur Notes upserten).
-- **--sync-deletes:** Punkte in Qdrant, die im Vault fehlen, sicher löschen (Dry-Run + Apply).
-- **--prefix**: CLI-Override für COLLECTION_PREFIX.
-
-Neu in 3.7.1
--------------
-- Chunk-Payloads enthalten nun
-    * `window` (Fenster inkl. Overlap, für Embeddings)
-    * `text`   (überlappungsfreies Segment, für verlustfreie Rekonstruktion)
-    * `start`, `end`, `overlap_left`, `overlap_right`
-- Embeddings werden aus `window` gebildet (mehr Kontext, bessere Retrieval-Qualität).
-- Die Offsets werden beim Build der Chunk-Payloads mitgegeben (`note_text`).
-
-Hash/Compare Konfiguration
---------------------------
-- Vergleichsmodus:
-    --hash-mode body|frontmatter|full
-    oder ENV: MINDNET_HASH_MODE | MINDNET_HASH_COMPARE
-- Quelle:
-    --hash-source parsed|raw          (ENV: MINDNET_HASH_SOURCE, Default parsed)
-- Normalisierung:
-    --hash-normalize canonical|none   (ENV: MINDNET_HASH_NORMALIZE, Default canonical)
-- Optional: --compare-text (oder ENV MINDNET_COMPARE_TEXT=true) vergleicht zusätzlich
-  den parsed Body-Text direkt.
-
-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)
