frank-primary runbook: record the allocator env and the e2e/FrankBook-Pro coupling

Two operational facts the cutover surfaced: PYTORCH_CUDA_ALLOC_CONF=
expandable_segments:True is part of the qualified shape (the plan fills VRAM to
its modelled headroom, so the default allocator's fragmentation fails
profile/graph capture — measured on the deployed unit), and the deploy's e2e
gate drives the admin open-links spec, which walks every guarded vhost
including 192.168.0.112:8989 on FrankBook-Pro — a sleeping Mac mini fails that
spec and reports DEPLOY INCOMPLETE while the engine is healthy.
