feat(quick-capture): add electron-based quick capture window

Implement a new electron-based quick capture window for rapid task entry from system tray. Features include:
- Standalone capture window with optimized UI for fast task entry
- Smart task parsing with natural language support (tomorrow, next week, etc.)
- Project/context tag autocompletion from vault
- Keyboard shortcuts for priority setting and quick actions
- System tray menu integration with keyboard accelerator
- Automatic window management and proper cleanup on close

The quick capture window provides a distraction-free interface for capturing tasks
without needing to switch context to the main Obsidian window.
