feat: index Reader LM 1.5B + BGE-M3 for OSINT pipeline

jinaai/reader-lm-1.5b (safetensors, 1 shard, 3.1 GB):
  HTML→Markdown local model. No Jina API needed.
  bgz7 → palette → O(1) HTML structure recognition.

CompendiumLabs/bge-m3-gguf (GGUF F16, ~1.2 GB):
  Multilingual embedding model. Replaces DeepNSM for non-English.
  bgz7 → palette → O(1) semantic similarity.

Together: Reader LM reads the web, BGE-M3 embeds it, AriGraph
stores it as SPO triplets, AutocompleteCache routes it at 17K tok/sec.
