v0.1.0 — Initial public release

PDF/EPUB textbook → AI-searchable markdown → structured, fully-cited notes. Five stages:
convert (0-token, silent-failure detection, column-aware reading order), chunk (heading-aware),
retrieve (local LanceDB semantic search with source weighting), write (template-driven,
citation-enforced, non-destructive), extract figures (geometric match + deterministic QC gate).
Bilingual READMEs and note templates; ships as skills an AI agent installs from AGENTS.md.
