Two prompt-only rules added to address follow-ups from #3:
1. Intra-scan dedup (new rule 4 in Correspondents section): when
processing multiple docs from the same sender in one scan batch,
reuse the correspondent name created earlier in the same session
instead of letting each doc create a fresh alias. Triggered by
paperless-AI creating 3 Praxis-Irle aliases in one batch (no native
batch-context plumbing; best-effort via prompt).
2. Short-brand prefix match (extension of Fuzzy-Regel): if OCR name is
a strict prefix of an existing correspondent (or vice-versa) and
the first 2 brand tokens match, use the existing correspondent.
Triggered by 'Hogan Lovells' creating a new correspondent despite
'Hogan Lovells International LLP' already existing.
Deployed via push_system_prompt.py --apply, container restarted, both
strings verified present in /app/data/.env (backup at
.env.bak.20260521T092606). Effectiveness will be observed as
multi-doc scans flow through.
