feat: 8 AI providers, rich text editor, agent notifications, UI contrast & font settings

- Add DeepSeek, OpenRouter, Mistral, Z.AI, LM Studio as AI providers with editable model names via Combobox in admin settings - Fix OpenRouter broken by normalizeProvider bug in config.ts - Convert agent-created notes from Markdown to HTML (TipTap rich text) - Add Notification model + in-app notifications for agent results - Agent notification click opens the created note directly - Add note count display on notebook and inbox headers - Fix checklist toggle in card view (persist state via localCheckItems) - Add checklist creation option in tabs/list view (dropdown on + button) - Fix image description ENOENT error with HTTP fallback - Improve UI contrast across all themes (input, border, checkbox visibility) - Add font family setting (Inter vs System Default) in Appearance settings - Fix CSS font-sans variable conflict (removed dead Geist references) - Update README with new features and 8 providers Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
