TodoApp v0.1.6

Added

✨ Features

• Search: Server-side full-text search over titles, descriptions, and tags via GET /api/todos?q=keyword (case-insensitive literal substring matching, backed by SQLite LIKE).
• Trash: Soft-delete todos and projects, then restore or permanently purge from a dedicated Trash view in the sidebar. Deleting a project cascades soft-delete to its todos in a single transaction; restoring is independent per item.

🎨 UI/UX

• Theme: Theme store now validates persisted values, exposes a reactive isDark for JS-styled surfaces (Chart.js), and tracks OS-level preference changes live.
• Statistics: Statistics panel charts now follow the active theme.

Changed

🔧 Refactoring

• Backend: DeleteProject is now a transactional cascade soft-delete; GetTodos accepts an optional q query for server-side search.
• Frontend: Added explicit dark-mode classes throughout components for consistency.

📦 Assets

• Icons: Optimized build/appicon.png (≈84% smaller) and build/windows/icon.ico.

📚 Documentation

• API: Documented search and the new trash endpoints in docs/API_DOCUMENTATION.md.
