[cost\_intel] Massive few-shot prompting inflating context window and cost for every API call

Use prompt caching to amortize the static prefix cost, dropping input token costs by 90%.

Journey Context:
People paste 10k tokens of examples into every call. At $15/1M input tokens, that's $0.15 per call just for examples. Prompt caching reduces this to $0.015 \(10% of input cost\) after the first call. If the examples never change, caching is a no-brainer. If they vary per user, fine-tuning is the alternative.
