WebtoonLens v0.7.0-alpha (debug build)

New: vocabulary saving with Anki-style spaced repetition

• Every single word you look up while reading is automatically saved to a personal vocabulary list (no manual save button - just tap a word and it's tracked).
• On-screen word highlighting is now 3-tier: blue (never saved), purple (saved, still being reviewed), grey (learned/graduated) - and the word you just tapped/circled stays yellow for the rest of that capture.
• In-app review screen (not an overlay - opens the real app): front/back flashcards with a ?? replay button, rated Again/Hard/Good/Easy to drive SM-2 scheduling, same algorithm family as Anki.
• Browse all saved words, edit their stored meaning, or delete them.
• Session history: long-press the floating bubble to see everything looked up since the bubble was started, with the same learned-status coloring.
• A "Vocabulary" tab with live stats, a configurable graduation threshold (1-90 days, default 21), and a master on/off toggle to disable saving entirely for a lighter-weight app.
• Copy support: long-press the translation popup to copy the Korean text to your clipboard.

UI cleanup

• The app now has a consistent dark theme throughout (previously the main screen was light while every popup was dark).
• MainActivity restructured into three tabs - Home (start the bubble), Vocab (review/browse/stats), Settings (bubble appearance, dictionary, translation API) - instead of one long scrolling page.
• Settings sections now render as clean rounded cards instead of plain stacked text.

Notes on this build

• Still a debug build (debug keystore), for testing/side-loading only.
• Verified on-device across this whole feature set: saving, highlighting, review scheduling, edit/delete, session history, and the new tabbed UI all confirmed working with no crashes.
