[FEAT] Add keyboard shortcuts to switch between HTML, CSS, and JS editor tabs

[devendra-w]

Problem

Currently users have to click on tabs to switch between HTML, CSS, and JS editors. There are no keyboard shortcuts for this, which slows down the workflow.

Expected Behaviour

• Ctrl+1 → switch to HTML tab
• Ctrl+2 → switch to CSS tab
• Ctrl+3 → switch to JS tab

Implementation Notes

• Add a keydown event listener in the main page component
• Map Ctrl+1/2/3 to setActiveTab("html"/"css"/"javascript")
• Make sure it doesn't conflict with existing shortcuts

Difficulty

Hi @Debmallya-03! I'd love to work on this. I'll add a keydown event listener in page.tsx, map Ctrl+1/2/3 to setActiveTab, and make sure it doesn't conflict with existing shortcuts like Ctrl+K. I've worked on similar keyboard interaction features in other open source projects. Can I be assigned?
