Description
#92 Phase 3: parallel notebook pre-execution for container repos — jcache project execute --executor local-parallel — compressing the cold case from 2,350s to ~950–1,550s.
- Pilot for OOM first: 16 GB runners, no worker knob (Decision 3 of #92 — does 16 GB survive 4 concurrent kernels on the heaviest DP lectures?)
- Roll out to the weekly cache builds
This is also the first step of #2 (standalone execution check of built notebooks), whose runtime budget depends on it.

Research direction
Start with the decisions and implementation context in issue #92, then inspect the jcache project execute --executor local-parallel entry point used by the reusable actions. Pilot the executor on 16 GB runners with four concurrent kernels, assess OOM behavior on the heaviest data-processing lectures, and verify the weekly cache builds before considering the work done.
