Hermes a834a1cb8b data: add trusted reference fingerprint for DeepSeek-V4.1-Flash (official api.deepseek.com) 
Collected with this tool against https://api.deepseek.com/v1, model id
deepseek-flash (API name: DeepSeek-V4.1-Flash), standard preset (8 cells x 25
samples), protocol one-token/v1, reasoning disabled via the openai-effort
adapter. 200/200 valid, 0 errors.

Unlike the bundled Zenodo samples, this reference is protocol-matched to the
package battery, so compare()/verify() against it is a direct comparison.

Deng-m1andCursor 232fbc6dd8 feat: initial release of llm-fingerprint-detector 
TypeScript library + CLI implementing single-token behavioral
fingerprinting of LLMs behind OpenAI-compatible APIs, per
'One Token Is Enough' (Bruckner, arXiv:2607.10252).

- Zero runtime dependencies (Node >= 18.17 built-in fetch)
- fingerprint / compare / verify API + llm-fingerprint CLI
- Jensen-Shannon divergence over per-cell answer distributions
- Reasoning-model aware (auto-disables hidden thinking channels)
- Bundled sample references for 11 popular models (CC-BY-4.0,
  derived from the paper's public Zenodo dataset)
- Unit + integration tests via node --test
