[counterintuitive] Prefixing prompts with 'Act as a senior developer' to improve code quality

Drop the persona and specify the exact constraints, tech stack versions, and architectural patterns instead.

Journey Context:
Persona prompting helped early models locate the right latent space, but modern RLHF'd models already operate at peak capability. 'Act as an expert' introduces verbose, sycophantic filler \('As a senior developer, I believe...'\) without actually improving the code logic. Specificity is the real lever: 'Use Python 3.12, FastAPI, and Pydantic v2' yields expert-level code, while 'Act as an expert' yields expert-level prose.
