RetrieX Prompt Precision Priority Fix

This patch intentionally avoids retrieval changes.

It does not add hard-coded keyword lists to the retriever and does not introduce a new core retrieval special case.

Goal

For technical questions where the retrieved chunk already contains the exact answer plus nearby comparison values, the model should answer the requested fact first and avoid adding runner-up products or adjacent values unless the user explicitly asks for comparison or alternatives.

Example:

• Question: Was ist der niedrigste Grenzwert fuer die Wasserhaerte, welcher mit einem Testomaten ueberwacht werden kann?
• Retrieved chunk may contain both Testomat 808: 0,02 °dH and Testomat 2000: 0,05 °dH.
• Expected answer should focus on 0,02 °dH / Testomat 808 and should not add the runner-up value unless requested.
