Pull request overview
This PR adds breadcrumb management functionality to the JavaScript Catcher, enabling automatic and manual tracking of events leading up to errors. Breadcrumbs provide a chronological trail of user actions, network requests, and navigation events that help debug issues by providing context.
Changes:
- Added automatic breadcrumb tracking for fetch/XHR requests, navigation events (History API), and optional UI clicks
- Introduced public API methods:
addBreadcrumb(),getBreadcrumbs(),clearBreadcrumbs() - Updated package to use @hawk.so/types v0.1.38 which includes Breadcrumb type definitions
