databricksFS
Databricks FileSystem backed by WorkspaceClient.
Extends BaseFileSystem. Routes I/O by absolute path:
/Workspace,/Users,/Repos,/Shared→ workspace objects API/Volumes/...(orcatalog.schema.volumeroots) → Unity Catalog Files API/dbfs/...→ DBFS API
Every primitive picks its API through DatabricksFileSystem.dispatch rather than re-branching by hand, and error normalization is inherited from BaseFileSystem, so a primitive here is just the SDK call.
