MANUAL RUN: hosted deploy of an x86 Hetzner box with uncommitted native/ crates (#760) #762

Follow-up to #760 (#373). The deploy container now has Rust, and rustybuns build box compiles an x86 box's crates with it, which was tested locally in the built image. It hasn't run on Cloudflare yet.

After the next codeSplitters deploy ships the new image:

• From the site, deploy a repo with a cpx Hetzner box and a native/ crate, with no native/dist/<crate>/linux-x64/ committed. The deploy step should show [native] building ... with cargo and finish inside the 13-minute budget.
• Do the same with a cax box. It should still be refused before anything is created.
• Check how long the container takes to start with the bigger image (about 1.2 GB on disk, up from 153 MB).
