Booklight 0.3.0

Added

• The reading timer returns — live. The Books-style reading home
  ships on all three platforms: a per-second timer (mm:ss) toward a
  20-minute daily goal on a semicircular gauge, a weekday streak row
  (a day counts after a full minute), a black continue-reading pill
  that opens your last book, and a toolbar mini-ring tracking today's
  progress. Reading minutes accrue only while a reader window is
  focused, and stay device-local by design.

Fixed

• Linux: the legacy watermark dialog sent opacity in the wrong unit
  (×10 instead of ×1000) — the same fix the newer sheet already had.
