fix(launcher): Gitea http URL; Wine Z: path + Wow.exe case check

- baked-gitea-channel: http:// for brassnet mirror.
- win-game-dir: map Unix /home/... to Z:\ under win32 (Wine folder picker).
- resolveGameDir + saveGameDir + patch paths use it; Wow.exe resolved case-insensitively.
- Version 1.0.6; README checklist for Wine.
