- Remove cli-node/src/paths.ts compat layer, migrate all cli-node
  internal usage to import targetPaths from @backstage/cli-common
- Use single-arg overrideTargetPaths('/root') where dir === rootDir
- Scope mockDir to each describe block in bump.test.ts to avoid
  shared state issues with overrideTargetPaths
- Remove unnecessary overrideTargetPaths from plugin-manager.test.ts
- Remove stale findPaths mock from createApp.test.ts
- Use overrideTargetPaths in getWorkspaceRoot.test.ts and cli-node tests
