Feature: Add Command Palette for Power Users

Summary

Add a command palette to the OpenFoodFacts Explorer app, enabling power users to quickly trigger navigation, search, and frequently-used features via keyboard shortcuts (like Cmd+K or /).

Motivation

A command palette increases productivity and accessibility for experienced users. It streamlines common tasks, fits developer workflows, and is now standard in most modern SaaS admin apps and code tools.

Desired Capabilities

• Open palette using keyboard shortcut (e.g., Cmd+K, /)
• Quick navigation to routes (search, settings, product pages, etc.)
• Trigger functions and actions (reload, clear cache, etc.)
• Fuzzy search and autocomplete
• Easy extensibility for adding future actions

Potential capabilities

• Quick navigation to content pages
• Individual settings search with inline toggling

Implementation Notes

• Consider popular libraries such as cmdk (MIT, Svelte-compatible)
• Follow Explorer's mobile-first and accessibility best practices
• Should be dismissible and non-intrusive
