[bug\_fix] go: module example.com/myrepo: reading at revision v1.0.0: unknown revision v1.0.0

Delete the git tag \`1.0.0\` and create a new tag with the \`v\` prefix: \`git tag v1.0.0\`. Go strictly requires the \`v\` prefix for semantic versioning in modules.

Journey Context:
A developer publishes a new version of their library, pushing a git tag named \`1.0.0\`. When they or a consumer tries to \`go get example.com/[email protected]\`, the command fails with 'unknown revision'. They check the Git repository and confirm the tag exists. They might try \`go get example.com/[email protected]\`, which also fails. After digging into \`go list -m -versions\`, they notice no versions are listed. The root cause is that the Go module system strictly enforces Semantic Versioning, which mandates a leading \`v\` \(e.g., \`v1.0.0\`\). Git tags without the \`v\` prefix are completely ignored by the Go module mirror and the \`go\` tool. Creating a proper \`v1.0.0\` tag fixes the resolution.
