Jevkit Brings Typed Jev Bindings to Rust

Jevkit gets the important abstraction right: Jev works best as a bounded decision service embedded in normal code, not as another chat client. The crate is promising glue for Rust routing and classification workflows, though its unofficial status and blocking-first client limit production readiness.

• –Compile-time validation catches missing questions, invalid variant counts, duplicate labels, and malformed schemas before requests are sent.
• –One request can batch Choice, Score, and Noul questions against the same state, matching Jev’s structured decision model. [Jev overview](https://www.jev.guide/en/learn/what-is-jev)
• –Typed decoding turns API labels into Rust enums and surfaces schema drift instead of silently accepting unknown values.
• –Confidence-aware results make escalation logic explicit: high-confidence decisions can proceed automatically while uncertain cases fall back to humans.
• –Declarative macros keep the crate single-package and dependency-light, but the unusual enum-inside-macro syntax is less ergonomic than conventional derive macros.
