* Bump Python package versions for 1.25.0 release

Release all 44 publishing workspace distributions with shipping changes since python-1.24.0, including the Python 3.10 removal. Use the approved minor bumps for Core/root, AG-UI, and Declarative, patch bumps for other changed stable integrations, and 261106 stamps for changed alpha/beta packages; no optional cohort-only bump. Update the Core standard-install cohort, apply strict API-based Core floors, and align exact hosting pins. Include the four Python Dependabot updates and the reviewed release batch manifest. Changelog includes the anticipated #10147 fix; the draft must wait for that PR to merge and be incorporated before release. Lab remains excluded from publication, with only its dependency lock updated.

* Fix SQL Server cancellation test exception-info narrowing

* Retain deprecated declarative MCP cache parameter and correct release notes

Accept legacy positive cache_max_size values with a deprecation warning, without restoring initialized-session caching. Keep per-invocation security isolation and the approved 1.5.0 version, document the compatibility behavior and remaining lifecycle migration, and extend real-protocol isolation tests for explicit legacy values. Remove the changelog claim and reference for still-open PR #9617.

* Simplify deprecated MCP cache parameter handling and undo skill edits
