Fixes #155

What this PR does

Deep research report (docs/jupyter-as-execution-layer-research.md) expanding on Timmy's initial spike, specifically addressing Rockachopa's request to research deeper into the JupyterHub/JupyterLab product suite and Papermill for real data pipelines.

Coverage

JupyterHub vs JupyterLab vs Notebook — clarifies the three distinct layers: Notebook (UI), JupyterLab (full IDE), and JupyterHub (multi-user server/orchestration). Includes JupyterHub REST API for programmatic server lifecycle management and the case for ephemeral per-run isolated kernel environments.

Papermill — the production notebook execution engine used at Netflix/Airbnb. Parameter injection via tagged cells, Python API + CLI reference, remote storage (S3/Azure/GCS), and Scrapbook for structured output collection. Direct comparison with hamelnb showing complementary (not competing) use cases.

The PR model for notebooks — the elegant answer to Rockachopa's question about making PRs to notebooks like code:

nbstripout as a git clean filter → clean diffs without output noise
nbdime for semantic cell-level diff/merge (not raw JSON)
nbval for pytest-based regression testing of notebook outputs
Full end-to-end agent PR workflow: read → modify cells → execute with Papermill → collect scraps → open Gitea PR

NotebookExecutor tool design — concrete API sketch for the short-term #1 item from the original spike.

hermes_runtime injection architecture — closes the biggest gap (no Hermes tool access in kernels).
