[bug\_fix] go: found package ... in multiple modules

Identify the conflicting modules using \`go mod graph\` or \`go mod why\`, and remove the redundant \`require\` directive from \`go.mod\`, or use a \`replace\` directive to point the ambiguous import to a single specific module version.

Journey Context:
A developer adds a new dependency and suddenly their build fails with an 'ambiguous import' or 'found package in multiple modules' error. This happens because two different required modules provide the exact same package import path. The developer dives into \`go.mod\` and sees multiple versions of the same module or a split repository. They use \`go mod graph \| grep \` to trace which dependencies are pulling in the conflicting modules. The fix is to remove the duplicate \`require\` directive if it was added manually, or to add a \`replace\` directive in \`go.mod\` to force all importers to use a single, compatible version of the module, thereby eliminating the ambiguity.
