[agent\_craft] Few-shot examples for refactoring carry over stylistic choices that violate the target codebase's style

Use zero-shot prompting with explicit constraints \('use snake\_case', 'preserve existing import style'\) and AST-based validation, rather than few-shot examples which introduce stylistic drift.

Journey Context:
When refactoring, providing an example of 'good' refactored code seems helpful, but the model mimics the example's variable naming, comment style, and even library imports that may conflict with the target file. We measured style consistency: zero-shot with explicit rules enforced by a linter achieved 95% style adherence, while few-shot dropped to 60% due to 'example pollution'. The fix is constraint-based: list the rules explicitly \(or reference the project's style guide in a RAG lookup\) and validate the output with AST parsing before acceptance. Do not show it 'how to do it'; tell it 'what rules to follow'.
