Hearthstone deck tracker for Linux, first public version

Reads the game's own Power.log: no screen capture, no image
recognition, no memory reading.

- deck tracking (remaining cards, draw chance, played cards fade in place)
- opponent panel (revealed cards, hand and deck counts)
- decks read from the game's offline cache, matched to the match
- card art in rows, full card on hover
- overlay and window modes, adjustable transparency, tray icon
- English and Turkish interface
- consistency tests over a real log corpus, cross-checked against Zone.log
