Booklight 0.1.0

The first release of Booklight — the reading-first rebuild of what
briefly existed as PDFGist (its release history was retired with the old
identity; the shelf imports those books on first launch).

Added

• The shelf — launch straight into your bookshelf: cover grid with
  reading progress, collections, search, and import that references your
  files in place (books are never copied; the shelf file is a single
  documented, stable library.json you can keep in your sync drive —
  see DATA-FORMAT).
• Reading — tabbed PDF (continuous scroll, two-page book view, zoom /
  fit-width, thumbnails, outline, full-text search) and EPUB (reflowable
  serif typography, chapter TOC, whole-book search) on macOS, Windows and
  Linux; continue-reading everywhere.
• AI at your elbow — selection translation, page / document summaries,
  and document chat, all streamed, all pointed at the provider you choose
  (GLM, DeepSeek, Kimi, Qwen, Doubao, SiliconFlow, Ollama, or any
  OpenAI-compatible endpoint). Your key stays on your machine.
• Annotations — three-color highlights, underline, strikeout, notes
  and bookmarks stored beside each book (sidecar JSON) or in the central
  store, ready for cloud-drive sync; byte-compatible across all three
  hosts.
• Light editing — a dedicated Tools menu: rotate, insert blank page,
  delete, extract, merge (in-memory; source files untouched) and AcroForm
  filling with export of the filled copy.
• Comforts — text-to-speech, printing, split view, password-protected
  PDFs, drag-and-drop import, interface language (follow system / 中文 /
  English), localized system chrome.
• Signed self-updates on all three platforms — Ed25519-verified
  manifest, SHA-256-checked download, installs only on your click.

Local-first data

Books stay in your folders and sync drives; progress and annotations ride
beside each book in sidecars; the shelf is one documented file. No
account, no telemetry — see DATA-FORMAT.
