v0.1.4

Fixes

• macOS: "Open With" now actually opens the file. Finder's Open With → Paperweight (and open -a Paperweight file.pdf) launched the app with an empty window instead of the document. macOS delivers the file via a system event, not a command-line argument, and Paperweight was only checking the latter. Fixed for both a fresh launch and for opening a second file while Paperweight is already running.
• Smoother zoom. Ctrl+scroll / trackpad pinch-to-zoom no longer queues a full page re-layout per wheel tick — it's capped to one per frame.

Under the hood

• Annotations (highlights, comments) now save to one file per document instead of one shared file that got rewritten in full on every single edit. This also fixes a real bug: having the same document open in two windows could silently overwrite one window's annotations with the other's stale copy.
• EPUB reading now releases pages once you've scrolled far past them, instead of keeping every visited page's chapter content in memory for the rest of the session — matching how PDF pages already behaved.
