[bug\_fix] go: github.com/myorg/[email protected]: verifying module: reading https://sum.golang.org/lookup/github.com/myorg/[email protected]: 404 Not Found

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/myorg/\*\) to bypass the public proxy and checksum database.

Journey Context:
A developer adds a private GitHub repository as a dependency in their Go project. When they run \`go mod tidy\`, the command hangs for a long time and eventually fails with a 404 Not Found error from sum.golang.org. They initially suspect a typo in the repository URL or an issue with their Git SSH keys, spending hours verifying Git access. However, the root cause is that the Go toolchain defaults to fetching modules and verifying checksums against the public Google proxy and checksum database. Since the repository is private, the proxy cannot fetch it, and the checksum database has no record of it. The fix is to set the \`GOPRIVATE\` environment variable, which instructs the Go toolchain to fetch and verify private modules directly from the source, bypassing the public proxy and sumdb entirely.
