Add search functionality with keyboard shortcut

[seanoliver]

Feature Request

Add search functionality to the site with keyboard shortcut support (Cmd+K / Ctrl+K).

Description

Implement a search feature that allows users to quickly find blog posts, projects, and other content across the site. Should include modern UX patterns like keyboard shortcuts for power users.

Proposed Implementation

• Search modal triggered by Cmd+K (Mac) / Ctrl+K (Windows/Linux)
• Real-time search across blog posts, projects, and other content
• Search by title, description, tags, and content
• Keyboard navigation (arrow keys, Enter to select, Esc to close)
• Consider using libraries like:
  • cmdk for command palette UI
  • flexsearch or fuse.js for client-side search
  • Or integrate with a search service

Design Considerations

• Mobile-friendly (tap to search, responsive modal)
• Accessibility (proper ARIA labels, keyboard navigation, focus management)
• Performance (index generation, lazy loading, debounced search)
• Visual feedback (loading states, no results messaging)

Context

This was identified as an improvement during the site enhancement phase but is a substantial feature addition rather than a cleanup task, so tracking as a separate issue for future implementation.
