gbrain import <subfolder> strips the folder from slugs and duplicates every page

Correction to my earlier note. With gbrain 0.44, gbrain import concepts (run from the vault root) treats concepts/ as the import root, so concepts/foo.md becomes slug foo, not concepts/foo. If the vault was already imported from its root, this creates a full duplicate of every page in that folder (here 2608 pages, 7.7 h of local embedding). Always import the vault root (gbrain import . from the vault); it skips unchanged files by hash. Cleanup: list slugs with gbrain list --limit 20000, take root-level slugs that also exist under concepts/, check for real root-level collisions first (e.g. README), then gbrain delete <slug> each one (a soft delete, recoverable for 72 h).
