v0.1.3

What's changed

• Fix: the ngram floor (minimum 3) is now enforced only in contiguous mode, where ngram is used. check(..., mode="subsequence", ngram=1) succeeds instead of raising — subsequence mode now truly ignores ngram, as documented (with a regression test; ADR-0011 amended).
• Docs: the RAG agent integration guide now gives whole-answer verbatim reuse and verbatim paraphrasing (mode="subsequence") equal standing alongside quotation verification, and introduces verbatim paraphrasing as a concept distinct from semantic paraphrase.
