[cost\_intel] Dynamically generating few-shot examples in the prompt without caching

Prefix the prompt with static few-shot examples and system instructions, enable prompt caching to reduce input costs by 90% and latency by 80%.

Journey Context:
People treat few-shot as dynamic when 90% of the examples are static. Caching only triggers if the prefix matches exactly. Cost drops from $3/MTok to $0.30/MTok. If the dynamic prefix shifts, cache misses and costs spike back to baseline.
