  PIPE-3073: Fix async deadlock in Prefect and document tier0futures
  - Refactor `_log_dask_summary` in `prefect_adapter.py` to execute entirely
    within a detached daemon thread. This prevents a critical deadlock where
    Prefect's `anyio` thread-portal and Dask's `scheduler_info` IO loop
    collide, effectively ensuring that sluggish telemetry or locked
    schedulers can never hang the root scientific pipeline.
  - Implement a 10s timeout on the telemetry retrieval as an absolute
    fallback mechanism.
  - Add comprehensive architecture diagrams and Tier0Futures use cases to
    `notes/prefect_guide.md`, explaining how Prefect and Dask interact
    during ALMA regression execution.
  - Update `notes/implementation.md` to reflect completed feature stability
    for the dynamic GUI flow routing and Dask artifacts plugin.
