Adds fuzzy search filter system

Implements a fuzzy search filter system using Fuse.js to enhance event searching.

This system allows users to quickly find events by typing partial matches of event titles or descriptions, providing visual feedback by dimming non-matching events. The filter persists during navigation and includes escape key support for quick clearing. It also includes performance optimizations like requestAnimationFrame debouncing.
