[bug\_fix] go: github.com/private-org/[email protected]: reading https://proxy.golang.org/...: 404 Not Found

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/private-org/\*\) so the Go toolchain bypasses the public proxy and fetches directly from the source VCS.

Journey Context:
A developer sets up a new private GitHub repository, tags a release, and attempts to use it in another project via go get. The command fails with a 404. They verify the tag exists on GitHub and their SSH keys work. They might clear the module cache or try different versions, but the error persists. The rabbit hole leads them to suspect a GitHub API issue or a typo in the URL. The actual root cause is that the Go toolchain defaults to fetching modules via the public proxy \(proxy.golang.org\). The public proxy cannot access private repositories and returns a 404. By setting GOPRIVATE, the toolchain is instructed to bypass the public proxy and checksum database for matching paths, fetching directly from the source repository, which resolves the 404.
