RetrieX Patch 17 - Accuracy Hotfix

Purpose

Patch 17 addresses the first concrete accuracy bug set after the YAML-only and governance cleanup. It keeps the YAML-only policy intact and does not introduce hard domain lists in PHP.

Covered issue classes

1. Product title anchoring for prompts that mention a product family plus variant suffix but omit an intermediate numeric family token. This prevents variant-specific questions from falling back to broader semantic hits.
2. RAG evidence confidence for aggregate/count-style portfolio questions. Semantic product hits are no longer enough to mark such answers as fachlich belegt unless aggregate evidence terms are present.
3. Commerce intent detection for product-seeking measurement prompts such as wanting to measure a parameter in an application context.
4. Commerce intent/shop query support for cable/accessory searches such as pH/Redox connection cables.
5. Prompt guardrail reinforcement so the model does not transfer accessory roles between separate shop product records.
