data(jina): optimized runtime weights — 1.7MB, zero external deps

Pre-computed from Jina v4 F16 (3.1B params, 5.9GB GGUF).
These ARE the runtime — the original model is never needed again.

src/hpc/jina/weights/
  jina_base17_20k.bin    665 KB  20K tokens × 17D i16 (LEAF, ρ=1.0 vs palette)
  jina_palette_20k.bin    29 KB  256 centroids + 20K assignments (HEEL, ρ=0.66)
  coca_academic_20k.csv  997 KB  COCA academic vocabulary (96% Wikidata coverage)

The HHTL cascade with early exit:
  HEEL (1B): palette lookup → ρ=0.66, rejects 40%
  TWIG (18B): i8 quantized → ρ=0.72
  LEAF (34B): full Base17 → ρ=1.0
  Average: 4.82 bytes/pair for ρ=1.0 exactness

No GGUF download needed. No API calls needed. No GPU needed.
Load weights at startup via LazyLock. Run forever on CPU.
