v0.2.0

• lib verify "quote" [--book ID] [--json] [--limit N]: catches misquoted book text,
  deterministically, no LLM. Book mode (--book) does a full scan of one book; shelf mode
  (no --book) attributes the quote across the library via FTS5 candidates.
• Verdicts exact / close / distorted / not_found / null, a word-level diff against
  the source for close/distorted, and grep-style exit codes with a script discriminator
  (exit 1 with empty stdout = error; exit 1 with output = "checked, not confirmed").
• 6th MCP tool, verify_quote — runs in a worker thread so a full book scan doesn't block
  the stdio server; all 6 tool descriptions are now in English (previously Russian).
