Benjamin Admin dac2a9f685 feat(rag): Legal-Metadaten — article_label + deterministische IDs + chunk_hash
Neues pures Modul legal_metadata.py (nur stdlib, lokal+CI testbar): §3-Normalisierung
section->article, strikte Header-Extraktion (Datum/Seiten-Rauschen -> kein Falsch-Zitat),
citation_style pro Regulierung (EU/CH=article, DE=paragraph), Urteil=Aktenzeichen statt §,
camelCase-Klarnamen (ProdHaftG), deterministische uuid5-Point-ID + chunk_hash (sha256).
documents.py verdrahtet build_legal_fields in den Payload-Build + document_version.
10 Tests gruen. Vertrag: rag_reingest_spec.md (§2/§3).

Benjamin Admin a459636bc4 fix(rag): HTML charset detection + opening block tag newlines
Two bugs fixed:
1. Opening block tags (<h3>, <div>) now also create newlines, not just
   closing tags. Fixes: gesetze-im-internet.de puts § inside <h3> which
   followed inline <a> text — § ended up mid-line, not at line start.

2. HTML charset detection from meta tag (charset=iso-8859-1). Files from
   gesetze-im-internet.de use ISO-8859-1, not UTF-8. The § byte (0xA7)
   was destroyed by UTF-8 decode. Now: try UTF-8 → check meta charset →
   fallback ISO-8859-1.

32 rag-service tests passing.

Benjamin Admin ddad58f607 fix(rag): strip HTML tags before chunking + D5 re-ingestion scripts
HTML files from gesetze-im-internet.de were decoded as raw UTF-8, keeping
<div>/<p> tags intact. The legal chunker regex requires § at line start,
which never matched inside HTML tags → 0% section metadata for HTML docs.

Fix: detect HTML content and strip tags before sending to embedding
service. Block elements become newlines, entities are decoded.
§ signs now appear at line starts → section detection works.

Also adds D5 re-ingestion scripts (reingest_d5.py + config) for
batch re-processing of all documents in Qdrant collections.

27 rag-service tests passing.

Benjamin Admin 93099b2770 feat(pipeline): structural metadata end-to-end (Blocks D2-D4)
D2: RAG service stores section/section_title/paragraph/paragraph_num/page
from embedding service chunks_with_metadata into Qdrant payloads.

D3: Control generator prefers section > article > section_title from
Qdrant, adds page to source_citation and generation_metadata.

D4: Validated with real BGB §§ 312-312k text. Found and fixed critical
bug where Phase 3 overlap destroyed the [§ ...] section prefix, causing
only the first chunk per document to have metadata. All subsequent
chunks lost section info.

Also fixes pre-existing lint issues (unused imports, ambiguous variable
names, duplicate dict key, bare except).

456 tests passing (58 embedding + 387 pipeline + 11 rag-service).
