[cost\_intel] Dynamically generating few-shot examples for every LLM call

Prefix prompts with static large context \(e.g., system prompts, giant few-shot lists\) and use prompt caching to cut costs by 90% and latency by 80%.

Journey Context:
Token bloat from repeating system instructions/few-shots silently 10x costs. Caching requires a strict prefix architecture. A common mistake is injecting dynamic variables \*before\* the static few-shots, which causes 100% cache misses. The static prefix must come first.
