bug: Installing Go SDK causes module size error

[eodevx]

Description

When running the command to get/install kreuzbergs sdk for golang I encounter two issues. The first one is that it pulls a version with incompatible in the name. The other is the repo being too large to clone because of git history

 go get github.com/xberg-io/xberg@latest

go: downloading github.com/xberg-io/xberg v4.9.9+incompatible
go: github.com/xberg-io/xberg@latest: create zip: module source tree too large (max size is 524288000 bytes)

Weirdly enough using this works:

(add-chat-function) go get github.com/kreuzberg-dev/kreuzberg/packages/go/v4@latest
go: downloading github.com/kreuzberg-dev/kreuzberg/packages/go/v4 v4.9.9

go: downloading github.com/kreuzberg-dev/kreuzberg v4.9.9+incompatible
go: downloading github.com/kreuzberg-dev/kreuzberg/packages/go v0.0.0-20260703063851-ecfa94b5fa08
go: added github.com/kreuzberg-dev/kreuzberg/packages/go/v4 v4.9.9```

### Steps to reproduce

run the `go get github.com/xberg-io/xberg@latest` command to install (official command on website as well as github)

### Relevant files and configuration

should be fixed with rc.17 - which is being published.

Keeping this open — the bare command is still broken. go get github.com/xberg-io/xberg@latest resolves against the repo root, which has no go.mod and still carries the legacy v4.x tags from the pre-rename history, so it pulls v4.9.9+incompatible and then fails the 500 MB module-zip cap on the Rust monorepo.

Working install today (the Go module lives in a subdirectory with its own tags):

go get github.com/xberg-io/xberg/packages/go@latest

Two things to fix here: (1) the docs/README still show the failing root command (installation.mdx, README) and should point at the packages/go path, and (2) ideally add a root module/vanity-import or prune the stale v4.x tags so the bare path stops resolving to old +incompatible versions.
