Feature: Built-in search bar to find events by title or description

[thbst16]

Description

For timelines with many events, users need a way to quickly locate specific events by searching text content rather than manually scrolling through decades.

Use Case

A user viewing NFL history wants to find all events related to "Packers" or "Super Bowl" without manually panning through 100+ years of history.

Proposed Solution

• Add showSearch prop to render a search input
• Search should match against title, description, and optionally custom fields
• Matching events should be highlighted and the timeline should auto-pan to the first result
• Provide prev/next navigation for multiple matches
• Support onSearch callback for custom search implementations

Example API

<Timeline
  data={data}
  showSearch={true}
  searchFields={['title', 'description']}
  onSearch={(query, results) => console.log(`Found ${results.length} events`)}
/>
