- Create adapters/types.js with comprehensive type definitions
- Create adapters/electron/fs.js for file system operations
- Prepare structure for future migration to Tauri/Flutter
This abstraction layer makes future platform migration easier
and enables better testing with mock adapters.

- Add previewDebounceTimers map to track debounce timers per tab
- Add updatePreview(tabId, immediate) with optional immediate flag
- Debounce preview updates during typing (300ms delay)
- Use immediate=true for tab switches and file loads
- Refactor _renderPreview as internal method
This significantly improves editor responsiveness when typing
in large markdown files.

CSS improvements:
- Standardize dark theme selectors to body[class*="dark"] pattern
- This ensures all dark themes (theme-dark, theme-dracula, etc.)
receive consistent styling
- Add semantic color variables (--text-primary, --bg-primary, etc.)
- Replace hardcoded colors with CSS variables in:
- Tab bar component
- Toolbar separator
- Pane resizer
- Status bar
- Add fallback values for backward compatibility
This improves maintainability and makes theming more consistent.
