Introduce keyboard shortcuts to the dashboard and add contributor docs. Adds a reusable useKeyboardShortcuts hook (with formatShortcutKey), a KeyboardShortcutsHelp modal component, and integrates shortcuts into App.tsx (registering keys like ?, Escape, /, ArrowLeft/Right, l, d and wiring store actions). Adds related styles (.glass-heavy, .kbd) to index.css. Also adds a comprehensive CONTRIBUTING.md with setup, workflow, testing, and PR guidelines.
