Add dynamic tray icon with usage display and comprehensive theming system

Implemented several major enhancements to the Claude Usage Widget: Features Added: - Dynamic tray icon with circular progress pie chart showing usage percentage - Configurable tray display mode (Session/Weekly) and refresh interval (10-300s, default 30s) - Optional percentage text overlay in tray icon (default: off) - Independent color customization for tray icon (normal/warning/danger states) - Static color mode toggle for both main window and tray icon (single color vs gradients) - Comprehensive theming system for main widget and settings window: * Background gradient customization * Primary and secondary text color controls * Title bar color with opacity slider * Border color with opacity slider - Collapsible settings sections with smooth animations (minimized by default) - Custom dark-themed scrollbar with purple accents matching app theme - Real-time theme synchronization between main and settings windows Technical Implementation: - Zero-dependency tray icon generation using Electron's built-in Canvas API via hidden BrowserWindow - IPC-based bi-directional communication for real-time theme updates - Persistent settings storage using electron-store - Conditional UI rendering for static vs gradient color modes - All changes maintain upstream compatibility (no external npm dependencies added) Files Modified: - main.js: Added icon generator window, tray icon generation, theme IPC handlers - preload.js: Added IPC methods for tray settings and theme management - src/renderer/app.js: Added theme application and usage data forwarding - src/renderer/settings.html: Added theming controls, collapsible sections, toggles - src/renderer/settings.css: Added styles for new UI components and custom scrollbar - src/renderer/settings.js: Added theme/tray settings logic with real-time updates Files Added: - src/icon-generator.html: Hidden window for canvas-based tray icon generation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
