[bug\_fix] go: ... is a program, not an importable package

Remove the import statement. If shared logic is needed, refactor the package main code into a separate library package \(e.g., package mylib\) and import that library instead.

Journey Context:
A developer wants to reuse some utility functions from another project's main.go. They add import example.com/foo to their code. The build fails with is a program, not an importable package. They try importing specific subdirectories, but the root package is what they need. They wonder if they can just change package main to package bar, but then the other project won't compile as an executable. The root cause is that Go strictly forbids importing a package named main. The main package is a special designation for executable programs and cannot be consumed as a library. The fix works because extracting the logic into a separate library package allows both the original executable and the new consumer to import the shared code without violating Go's package rules.
