Bugfix Release: OpenZFS CLI Snapshot Discovery, Root Dataset Resolution & Configuration Guide

🐛 Bug Fixes & Stability

• OpenZFS Provider Initialisation & Snapshot Timestamps:
  • Fixed an issue in RootFolder where ProviderRegistry was erroneously queried with provider_type ("cli") instead of filesystem_type ("zfs"), which caused auto-discovered ZFS roots to silently fall back to GenericProvider / FilesystemSnapshotProvider.
  • Ensured ZfsProvider.create_snapshot_provider properly forwards config.dataset_name to ZfsCliSnapshotProvider.
• Root-on-ZFS Path Resolution (/ & Container Mount Prefixes):
  • Fixed dataset matching in ZfsClient.find_dataset_by_path when the root filesystem dataset is mounted at / and passed into the container via /host (mount_prefix: "/host").

📚 Documentation

• Comprehensive Configuration & Architecture Guide:
  • Created docs/configuration-guide.md with deep-dives into path resolution formulas, provider use-cases (btrbk, Snapper, OpenZFS), and dynamic snapshot-specific UID/GID mappings.
