CHANGELOG

Vercel Configuration Support: Introduced a new vercel.json configuration generator for seamless deployment on Vercel. This ensures that both scaffolded projects and built ones run the same commands, enhancing consistency and ease of deployment.
Widget Source Copying: Added functionality to ship FileSource widget sources with the build output. This ensures that widget files are correctly included in the build, preventing runtime errors due to missing files.
Pagination Handling: Implemented a utility to handle pagination for MCP list operations. This ensures that all items are retrieved across multiple pages, preventing data loss in large datasets.

Dynamic Plugin Options: Enhanced the DynamicPlugin class to store initialization options, allowing for better management and reuse of plugin instances across different registries.
Guard Storage Error Handling: Improved error handling for storage backends in the Guard module. The system now throws a GuardStorageUnavailableError when the configured storage cannot be reached, ensuring that rate limits are enforced correctly.

Session ID Validation: Fixed an issue where session IDs were not being validated correctly across deployments. This prevents session fixation attacks by ensuring that only server-minted IDs are honored.

fix(plugins): built-in plugin bugs from #647 (cache, approval, remember, CodeCall) by @frontegg-david in #650
fix: several instances, the Vercel build and list paging from #648 by @frontegg-david in #651
fix(ui): widget sizing, .tsx bundling and host theme from #649 by @frontegg-david in #652
