[bug\_fix] ambiguous import: ... is provided by ... and ...

Remove the redundant \`replace\` directive in go.mod if using a Go workspace \(go.work\), or ensure that only one module in the workspace provides the package.

Journey Context:
A developer sets up a multi-module Go workspace using \`go work init\` to work on a service and a shared library simultaneously. The service's go.mod has a \`replace\` directive pointing to the local shared library. When they run \`go build\`, they get 'ambiguous import'. They dive into the rabbit-hole of checking import paths, thinking they misspelled something or have a circular dependency. They try deleting the go.sum files. The actual root cause is that the go.work file already tells the Go toolchain to use the local version of the shared library, but the \`replace\` directive in go.mod is also telling it to use a local version. The toolchain sees two different directives for the same module path and gets confused, resulting in the ambiguous import error. The fix is to remove the \`replace\` directive from the go.mod file, as go.work supersedes it for local development, or use \`go work sync\` to manage the replacements.
