[bug\_fix] go: module \[...\] found, but does not contain package \[...\]

Correct the case sensitivity of the import path to exactly match the \`module\` directive in the dependency's \`go.mod\` and the actual repository path \(e.g., change \`github.com/MyOrg/Repo\` to \`github.com/myorg/repo\`\).

Journey Context:
A developer imports a package \`github.com/MyOrg/MyRepo/sdk\` and runs \`go build\`. The tooling successfully downloads the module \`github.com/MyOrg/MyRepo\` but then fails, claiming the \`sdk\` package doesn't exist inside it. The developer checks GitHub and the \`sdk\` folder is clearly there. The root cause is case sensitivity. Git on Windows and macOS is case-insensitive by default, allowing developers to use varying casing in imports. However, the Go module filesystem and toolchain are strictly case-sensitive. If the \`go.mod\` of the dependency declares \`module github.com/myorg/myrepo\` \(lowercase\), but the import uses \`MyOrg\` \(uppercase\), the Go toolchain fails to map the import path to the module path, treating the requested package as missing. Fixing the import path to exactly match the lowercase \`module\` directive resolves the build.
