feat: remember window state and show native unread badges

[milind-soni]

What this adds

• restores the main window’s normal bounds and maximized state between launches
• keeps restored windows reachable after monitor, resolution, or DPI changes
• mirrors visible unread conversations to the macOS/Linux app badge and a Windows taskbar overlay
• validates renderer IPC and caps the native unread count

Safety and provenance

This is an independent clean-room implementation based on OpenMausBot’s existing Electron shell and the public Electron APIs. No code or assets were copied from the reconstructed Grok Bot repository. The saved file contains only window geometry and maximized state.

Validation

• pnpm typecheck
• pnpm vitest run electron/window-state.test.mjs src/lib/unread.test.ts (6 tests)
• pnpm build
• pnpm check:electron (42 Electron modules)
