[synthesis] Entangled prompt pipelines causing untestable AI products

Treat prompt fragments as immutable, versioned functions with typed inputs/outputs, and compose them via code rather than building mega-prompts via string concatenation.

Journey Context:
Traditional software has functions; AI products often have massive, concatenated prompt strings. As features are added, developers append instructions to the prompt. Because LLMs are sensitive to ordering and context, changing a prompt for Feature A breaks Feature B. This creates a tangled web where no one can deploy a prompt change without breaking the whole product. The fix is to apply functional programming concepts to prompts: small, isolated, versioned prompt templates with defined schemas, orchestrated by deterministic code.
