frank-default-large: full 262144 context, 1 slot

User request 2026-08-19 (second pass): parallel slots degraded
performance. PARALLEL=1, CTX_SIZE=262144 (native max, -c equals the
per-slot context with one slot). Concurrent requests queue on the
single slot; the server never preempts a running generation.
pi models.json contextWindow/maxTokens back to 262144 (outside repo).
Docs updated to match.
