Double barrel ReACT agent architecture: LLM does the writing.

Double barrel ReACT agent architecture: LLM does the writing. Jev does all the deciding. Tool call decisions and agent loop state are all decided by Jev. LLM writes user output, and tool inputs, where needed. Included real-world benchmarks against basic ReACT agent architecture. The strongest successful comparison showed: - 77% fewer LLM input tokens with Jev. - 17% fewer uncached input tokens—caching matters. - Two LLM calls instead of five.
