/**
 * Determines if a path in a replace directive is a local filesystem path
 * or a module path.
 *
 * According to Go's module documentation:
 * - If the first path element contains a dot, it's treated as a module path
 * - Otherwise, it's a local path
 *
 * Examples:
 * - "./common" -> local
 * - "../libs/common" -> local
 * - "/absolute/path" -> local
 * - "github.com/foo/bar" -> module
 * - "example.com/pkg" -> module
