weights v1 — activated RAG adapters

The three activated LoRA adapters qi loads at startup, in GGUF.

Hugging Face publishes these as safetensors under granitelib-rag-r1.0; these
are the GGUF conversions, which is why they live here rather than being mirrored
from upstream. The other two intrinsics — citations and hallucination_detection —
are plain LoRAs and are fetched from Hugging Face directly.

Activated means the adapter engages only after its invocation tokens, so the base
model's KV cache for the prompt stays valid. For answerability, which runs once
per source read, that is the difference between 16.98s and 0.04s per call.
