copilot-swe-agent[bot] a5c9ffbef7 Fix CSV import regression with root group names ...

Fix the issue where CSV export/import creates nested root groups when the database has a custom root group name.

Added comprehensive tests to verify the fix works for both custom and default root group names, and preserves existing behavior for single-level groups.

Implement heuristic approach for CSV import root group detection:

- Analyzes all CSV rows before processing to find consistent first path components
- Only skips the first component if it appears in 80% or more of paths
- Handles absolute paths (starting with "/") by ignoring them in analysis
- Preserves existing behavior when no clear common root is found
