fix: smart uninstaller cleanup + prevent nested .ragcode dirs

- Uninstaller derives scan roots from registry, Qdrant file_path payloads,
  JetBrains/VSCode/AI-IDE configs — no more hardcoded directory guessing
- findWorkspaceRootFromFilePath: walk up from Qdrant payload to workspace root
- detectIDEProjectParents: reads recentProjects.xml, storage.json, resolveIDEPaths
- detector: removed .ragcode from workspace markers (prevents hijacking root detection)
- resolver: applyNestedOverride centralized — prevents split-indexing on sub-dirs
