[bug\_fix] go get github.com/internal/[email protected]: unrecognized import path or 404 Not Found via proxy.golang.org

Set the \`GOPRIVATE\` environment variable to include the internal module path \(e.g., \`go env -w GOPRIVATE=github.com/internal/corp\` or \`GOPRIVATE=github.com/internal/\*\`\).

Journey Context:
A company sets up an internal Git repository for a shared Go package. A developer tries to \`go get\` it, but the build hangs or fails with a 404. They check their Git credentials and can clone the repo fine via \`git clone\`. The rabbit hole begins: they assume it's an SSH key issue, a Git config issue, or a firewall block. They try injecting Git credentials into the Go toolchain. The actual root cause is that the Go toolchain defaults to fetching modules via the public \`proxy.golang.org\` and \`sum.golang.org\`. Since the internal repo is private, the public proxy cannot find it. Setting \`GOPRIVATE\` tells the Go toolchain to bypass both the public proxy and the checksum database for matching module paths, forcing it to fetch directly from the version control system using the developer's local Git credentials.
