Subject: [PATCH 1/5] Bump Python package versions for 1.22.0 release

Update all published Python packages because Python 3.15 metadata changed across the workspace. Apply minor bumps to stable packages with breaking or additive API work, patch Orchestrations, stamp alpha and beta packages with 261015, refresh the core[all] release cohort, raise Core floors only for packages that require the coordinated content-identity contract, and update release notes and lockfiles.

+> [!IMPORTANT]
+> **Python 3.15 support:** The core framework and root `agent-framework` package now support Python 3.15, but not every package, optional extra, or feature supports it yet because of upstream dependency constraints. Before upgrading, check the README for each package and extra you use. The [Python README](https://github.com/microsoft/agent-framework/blob/main/python/README.md#python-315-limitations) summarizes the currently known limitations.

Subject: [PATCH 2/5] Address Python 1.22 release review feedback

Align all Hosting adapters on the co-released Hosting version, remove the intentionally unpublished Lab package from the release cohort, document the mixed-version persisted-state constraint, and add the merged Message string fix to the changelog.
