Merge pull request #134: fix(shared): bind platform when creating group manager (v3.9.8)

Add a PostgreSQL integration regression test for new-platform-group session creation. The production failure was a missing Platform parameter in the group_managers insert, leaving @Platform in SQL and causing PostgreSQL 42883. Bump version to 3.9.8.
