v0.1.0

• Deterministic pipeline turning FB2, EPUB, DOCX, HTML, TXT/MD, and text-layer PDF into
  clean, token-counted Markdown chapters — byte-identical output for identical input.
• Quality gate: five metrics (coverage, structure, garbage, encoding, dehyphenation) score
  every book into ok / review / failed, with lib doctor for diagnostics.
• lib find: FTS5 full-text search across chapters, titles, and authors, with RU/EN
  stemming and JSON output.
• Built-in MCP server (lib serve / librarian-cli): 5 read-only tools over the same
  reader core, so Claude can browse, search, and pull chapters under a token budget —
  deterministic RAG with no embeddings, no network, no API keys.
• Offline-vendored o200k_base tokenizer — no network calls at install or runtime.
• CLI: ingest · list · get (spec | --budget) · find · info · doctor · reingest · rm · serve.
