Use DuckLake on MotherDuck

Source Of Truth

• Prefer current MotherDuck DuckLake docs first.
• Use the upstream DuckLake and DuckDB extension docs only to clarify extension-level behavior that MotherDuck docs reference.
• Keep the guidance aligned with the documented product posture:
  • native MotherDuck first
  • MotherDuck's DuckLake docs define the supported product surface and lifecycle/compatibility limits; verify the current DuckDB/DuckLake version matrix instead of preserving an upstream version or product status in the prompt
  • fully managed, BYOB, and own-compute paths are distinct
  • maintenance and compaction are explicit operations, not background magic
