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

Change the module declaration in go.mod from \`module myproject\` to a path containing a dot in the first element, such as \`module github.com/user/myproject\`, and update all import paths accordingly.

Journey Context:
A developer initializes a new Go project locally using \`go mod init myproject\`. Everything works fine with \`go run main.go\`. However, when they try to install the binary using \`go install myproject\` or when a colleague tries to pull the project and build it, the build fails with 'malformed module path'. The developer goes down a rabbit hole checking their Go installation and environment variables, thinking it's a local bug. They try adding a \`replace\` directive, which masks the issue locally but fails in CI. The root cause is that Go enforces a convention where the first path element of a module path must contain a dot \(like a domain name\) to ensure global uniqueness and prevent collisions with standard library packages. The \`go install\` command strictly validates this, while \`go build\` might be more lenient for local execution. Changing the module path to a proper URL-like format resolves the validation error globally.
