[bug\_fix] import cycle not allowed

Break the circular dependency by either: \(1\) extracting the shared types or functions into a third package, \(2\) using interfaces to invert the dependency, or \(3\) moving one of the imports to a later point in the code \(e.g., via a lazy initialization pattern\).

Journey Context:
A team was refactoring a monolith into smaller packages. They created package \`a\` that imported package \`b\`, and package \`b\` that imported package \`a\` \(perhaps through a common utility\). The build failed with 'import cycle not allowed'. The developer tried to remove the import from \`b\` but needed a type from \`a\`. They spent hours trying to inline code or use forward declarations, but Go does not support circular imports. The solution was to create a new package \`c\` containing the shared type that both \`a\` and \`b\` needed. After moving the type to \`c\`, both packages imported \`c\` and the cycle was broken. The root cause: Go's compiler disallows circular imports to prevent infinite recursion and ensure clear dependency graphs.
