[synthesis] Image text transcription hallucinations vs over-conservative refusals

Instruct the model explicitly: 'Transcribe the exact text. If any part is illegible, indicate it with \`\[illegible\]\` rather than guessing.'

Journey Context:
Without explicit instructions, GPT-4o will confidently output a clean string even if the image is blurry, masking the uncertainty. Claude 3.5 Sonnet is more conservative and will refuse to read slightly blurry text, breaking the pipeline. Gemini might summarize the text instead of transcribing it. Instructing the model to mark uncertainty aligns their behaviors: GPT stops guessing, Claude becomes more willing to try, and Gemini focuses on transcription over summarization.
