Go clients need one GOPROXY for internal and public modules; goproxy has no virtual type, so a local goproxy repo and proxy.golang.org cannot be served together.
- union member `@v/list`s; compute `@latest` over the union (highest release, else highest prerelease)
- 302 `@latest` and `.info`/`.mod`/`.zip` to the first member with that version, root-relative and `no-store`; probe `.info` for unlisted pseudo-versions
- validate case-encoded module paths and versions
- fail closed with 502 on a member error, skip members answering 404/410
- cache merged lists, keyed on list and version owners, and module misses for the merge TTL
- add `docs/goproxy/virtual.md` and a stock `golang:1.25` e2e-docker case
