[research] Inverted logic in negation queries

Avoid relying on the LLM to process complex negations in user prompts. Rewrite queries into affirmative statements internally, or explicitly validate the presence/absence of the negated condition in the output.

Journey Context:
LLMs struggle significantly with negation, often ignoring 'not', 'never', or 'except' in prompts. If a user asks for code that avoids a specific deprecated API, the LLM is highly likely to use that exact API. Translating the negation into an explicit affirmative constraint \('Use the modern API X instead of Y'\) mitigates this failure mode.
