Description: Motivation and Context In order to allow the initial connection to have contextual information in the reactive chain, the McpClientSession should be able to transform the McpClientTransport#connect result, e.g. to attach Context items. This change introduces a new constructor for sessions that makes it possible. How Has This Been Tested? A new test specifically for validating the presence of a context item has been added. Breaking Changes Deprecating the old McpClientSession constructor. Types of changes Bug fix (non-breaking change which fixes an issue) New feature (non-breaking change which adds functionality) Breaking change (fix or feature that would cause existing functionality to change) Documentation update Checklist I have read the MCP Documentation My code follows the repository's style guidelines New and existing tests pass locally I have added appropriate error handling I have added or updated documentation as needed Additional context N/A
