Shkarko DatabricksCLI 0.299.0

CLI
- Moved file-based OAuth token cache management from the SDK to the CLI. No user-visible change; part of a three-PR sequence that makes the CLI the sole owner of its token cache (#5056).
- Remove the --experimental-is-unified-host flag and stop reading experimental_is_unified_host from .databrickscfg profiles and the DATABRICKS_EXPERIMENTAL_IS_UNIFIED_HOST env var. Unified hosts are now detected exclusively from /.well-known/databricks-config discovery. The experimental_is_unified_host field is retained as a no-op in databricks.yml for schema compatibility (#5047).
- Added interactive pagination for list commands that have a row template (jobs, clusters, apps, pipelines, etc.). When stdin, stdout, and stderr are all TTYs, databricks <resource> list now streams 50 rows at a time and prompts [space] more [enter] all [q|esc] quit. ENTER can be interrupted by q/esc/Ctrl+C between pages. Colors and alignment match the existing non-paged output; column widths stay stable across pages. Piped output and --output json are unchanged (#5015).
- Added experimental OS-native secure token storage opt-in via DATABRICKS_AUTH_STORAGE=secure. Legacy file-backed token storage remains the default (#5008, #5013).
- Fixed a panic in databricks warehouses update-default-warehouse-override when invoked without all required positional arguments (e.g. picking a warehouse from the interactive drop-down and then hitting an index-out-of-range crash). The command now validates arguments up front and returns a usage error. Fixes #5070 via #5079.
Bundles
- Translate relative paths in alert_task.workspace_path on job tasks to fully qualified workspace paths, matching the behavior of other task path fields. Applies to both regular tasks and for_each_task nested tasks (#4836).
Dependency updates
- Added github.com/zalando/go-keyring as a new dependency (dormant until a later release enables experimental secure-storage for OAuth tokens) (#5008).
