[Feature]: Add keyboard shortcut navigation ('j'/'k' and arrow keys) for browsing directory cards #25

Feature Name / Concept

Vim-style ('j' / 'k') and arrow-key card navigation

Area of Impact

Web App UI / UX (devshelf.ritualdev.in)

Problem or Opportunity

Power users and keyboard-first developers frequently visit DevShelf looking for tools without reaching for the mouse. We currently support / to focus the search bar, but navigating down through cards requires manual mouse scrolling.

Proposed Solution & Technical Details

• When search input is not focused, pressing j or ArrowDown highlights the next resource card with an active cyan glow.
• Pressing k or ArrowUp moves focus to the previous card.
• Pressing Enter opens the highlighted item's repository / website in a new tab.
• Pressing c copies the card URL directly to the clipboard.
