[bug\_fix] go: cannot find module for path

Run \`go mod init \` in the project root to create a go.mod file, enabling module mode for the project.

Journey Context:
A developer creates a new project in an arbitrary directory outside their GOPATH, writes a main.go importing an external package like \`github.com/gin-gonic/gin\`, and runs \`go build\`. The build fails, stating it cannot find the module for the path. The developer might try \`go get\`, which also fails or does nothing. The root cause is that the Go toolchain is operating in a context where it doesn't know which module the current code belongs to because there is no go.mod file. Modern Go \(1.16\+\) defaults to module mode, but requires a go.mod file to track dependencies and define the module root. Running \`go mod init\` creates this file, establishing the module boundary and allowing the toolchain to properly fetch and resolve external dependencies.
