feat: Kivy-based Android companion app mirroring Badger2040 UI

[Copilot]

Addresses the request to make beanOS available as an Android app. Adds a self-contained Python/Kivy companion app under android/ — same language as the codebase, builds to APK via buildozer. The UI closely mirrors the Pimoroni Badger2040 E-Ink display in both visual style and interaction model, and is locked to landscape orientation.

New: android/

• main.py — Kivy app with 4 screens (Home, Stats, Wartung, Achievements) and the same data model and all 15 achievement definitions as the Badger2040 version. Local persistence via beanos_data.json. Tracks caffeine and bean consumption estimates alongside drink counts.

  Home screen mirrors main_screen.svg:

  • Three tappable CounterBox widgets (ESPRESSO, CAPPUCCINO, ANDERE) fill the main area between the title bar and nav — tapping ESPRESSO or CAPPUCCINO adds +1 directly; tapping ANDERE opens the GETRÄNKEAUSWAHL popup (Lungo, Iced Latte, Affogato, Shakerato, Espresso Tonic, Other — each with today's count and a + button)
  • Bottom action bar: Tageswechsel (reset today with confirmation) | Statistik | Wartung | Menü
  • Menü popup mirrors the Badger2040 menu: Bohnen · Statistiken anzeigen · Tagesstatistiken zurücksetzen · Datum ändern · Wartungshistorie · Achievements · Information

  Wartung screen mirrors maintenance_menu.svg: all 5 maintenance tasks (Reinigung, Entkalken, Brühgruppe reinigen, Mühle reinigen, Grundreinigung) with last-done date, overdue ! indicator, and Erledigt button.

  Statistik screen mirrors statistics_view.svg: per-drink rows with per-day averages, inverted summary row at bottom.

  Visual style: E-Paper / E-Ink throughout — white paper background, black title bars with white text, 1 dp bordered counter boxes, thin separator lines, custom E-Ink progress bar.

• buildozer.spec — targets Android API 33, arm64-v8a + armeabi-v7a, locked to orientation = landscape

• README.md — quick-start for desktop testing and full APK build instructions

# Desktop / CI smoke test
pip install kivy && cd android && python main.py

# Android APK
pip install buildozer && cd android && buildozer android debug

Updated

• README.md — Android companion entry in quick-features list
• ROADMAP.md — "Mobile companion" item replaced with implemented checklist + future sync/notification work
• .gitignore — beanos_data.json excluded

Done in c51733e. The app now uses an E-Paper visual style matching the Badger2040 display:

• White paper background everywhere
• Black title bars with white text on every screen (same as the hardware SVG screens)
• Three bordered counter boxes on the home screen (ESPRESSO | CAPPUCCINO | GESAMT) with a 1 dp black border
• Thin black separator lines between list rows
• Section headers as smaller black bars
• Custom E-Ink progress bar (white box, black outline, black fill)
• Monochrome nav bar: active tab inverted (white on black), inactive tabs black on white

Die App soll landscape zur Anzeige erfordern.

Done in 652225e. The app now requires landscape:

• buildozer.spec: orientation = landscape — Android will refuse to rotate to portrait
• Home screen redesigned for landscape: counter boxes + streak/caffeine info on the left (60 %), two large quick-add buttons stacked on the right (40 %), with a 1 dp vertical E-Ink separator — matches the wide Badger2040 display ratio

Das Design soll möglichst ähnlich dem original auf dem Badger sein. Die Felder für Espresso und Cappuccino sollen gleich der Button +1 des jeweiligen Getränks sein. Bei Sonstige soll sich das Menü der Sonstigen Getränke öffnen.
Damit brauchen wir keine anderen Buttons für die Getränke. Die Buttons am unteren Rand sollen sein:
Tageswechsel, Statistik, Wartung, Menü. Menü soll das Menü wie auf dem Badger öffnen.

Done in 4f29766. The app now closely mirrors the Badger2040 original:

• Three tappable counter boxes (ESPRESSO, CAPPUCCINO, ANDERE) fill the main area — tapping ESPRESSO or CAPPUCCINO adds +1 directly; tapping ANDERE opens the GETRÄNKEAUSWAHL popup (Lungo, Iced Latte, Affogato, Shakerato, Espresso Tonic, Other — each with current count and + button). No separate drink button screen needed.
• Bottom bar: Tageswechsel | Statistik | Wartung | Menü
• Menü popup: Bohnen · Statistiken anzeigen · Tagesstatistiken zurücksetzen · Datum ändern · Wartungshistorie · Achievements · Information — same as the Badger2040 menu_options
• Wartung screen: mirrors maintenance_menu.svg — all 5 tasks with last-done date, overdue ! indicator, and Erledigt button
• Statistik screen: mirrors statistics_view.svg — per-drink rows with per-day averages, inverted summary row at bottom
