Pull request overview

This PR aims to make Quark/UC directory creation more robust by actively re-fetching the created folder’s file ID after MakeDir, reducing errors caused by eventual consistency between Quark’s cache and OpenList’s database.

Changes:

• Changed QuarkOrUC.MakeDir to return the created/existing directory object (model.Obj) instead of only error.
• After issuing the create-folder request, repeatedly lists the parent directory and searches for the new folder by name with backoff + context cancellation support.
• Special-cases a known Quark/UC conflict message to continue lookup rather than failing immediately.
