Initial commit: macOS clipboard manager menu bar app

Tauri 2 + React 18 + TypeScript + Tailwind CSS v4 + SQLite (rusqlite)

Features:
- Menu bar app with tray icon (no dock icon)
- Global hotkey Cmd+Shift+V
- Clipboard polling every 500ms (text, images, file paths)
- SQLite FTS5 full-text search
- Pin/unpin entries, auto-trim, context menu
- Settings panel (launch at login, show images, max history, clear all)
- Dark/light mode following macOS system preference
- Frameless floating window, closes on blur

Testing:
- 27 Rust unit tests (db, clipboard, FTS5, trim, settings)
- 31 TypeScript component tests (vitest + @testing-library/react)
