[bug\_fix] go: malformed module path "my-module": missing dot in first path element

Change the module path in \`go.mod\` to include a dot in the first path element, such as \`example.com/my-module\` or \`github.com/user/my-module\`.

Journey Context:
A developer initializes a new Go module locally using \`go mod init my-module\`. They write some code and it works perfectly on their machine. Later, they try to use it as a dependency in another project, or they try to run \`go install my-module\`. The toolchain rejects the module path. The developer goes down a rabbit hole wondering if they need to register "my-module" somewhere, or if there's a DNS resolution issue. They try adding a go.mod file to the dependent project or tweaking GOPATH. The root cause is that Go 1.13\+ introduced strict validation for module paths: the first path element \(before the first slash\) must contain a dot to be considered a valid domain name, ensuring module paths are globally unique and resolvable. Changing \`go.mod\` from \`module my-module\` to \`module github.com/username/my-module\` fixes the issue.
