Client-side chat requests

Chat requests in Gram Elements now execute client-side, simplifying the architecture and improving responsiveness.

The chat handler has been removed from the server package as chat requests now happen directly from the client. A new session handler has been introduced for backend implementations that need server-side session management.

Features

• Client-side chat requests - Chat requests now execute directly from the client, reducing server-side complexity and improving response times.
• Session handler - A new session handler has been added to the server package for consumers who need backend session management.

Bug fixes

• TypeDoc improvements - Fixed TSDoc comments for multiple type definitions in the Elements library, improving developer documentation.
