CodeBench: reqwest 0.13 + Docker volume cache + rust:latest

- reqwest 0.12 → 0.13, rustls-tls → rustls (golden, Dockerfile, promptit)
- Docker volume cache: kipina-cargo-registry + kipina-cargo-target
- rust:latest (1.94) + cmake (aws-lc-sys vaatii)
- Dockerfile yksinkertaistettu — esikäännös ei toimi, volume hoitaa
- Golden example 10/10 testattu uudella setupilla
