Pull request overview

This PR introduces a new Appcues Web browser-mode destination for the Segment Actions framework. The implementation includes four core actions (track, page, identify, and group) with appropriate field mappings and a custom flatten utility function for handling nested data structures.

Changes:

• New Appcues Web browser destination with support for track, page, identify, and group events
• Custom flatten function to handle array-to-string conversions while preserving nested objects
• Comprehensive test coverage for all actions and initialization logic
• Region-based script loading (US/EU) with configurable URL detection
