feat: improve Crew search while resetting their memories

Some memories couldn't be reset due to their reliance on relative external sources like `PDFKnowledge`. This was caused by the need to run the reset memories command from the `src` directory, which could break when external files weren't accessible from that path.

This commit allows the reset command to be executed from the root of the project — the same location typically used to run a crew — improving compatibility and reducing friction.
