Dependency bounds test failed

Automated dependency bounds test mode failed before dependency upper-bound validation could run.

The weekly dependency maintenance workflow kept only dev dependency updates for the generated PR, if any, and skipped dependency range updates for this run.

### lower scenario (lowest-direct)

- Package: `agent-framework-core`
- Project path: `packages/core`

```
Task 'pyright' failed for packages/core at resolution 'lowest-direct'.

Workflow run: https://github.com/microsoft/agent-framework/actions/runs/27952164461

Start with the linked workflow run and inspect the dependency-bounds workflow for the lowest-direct resolution of packages/core. Read agent_framework/_telemetry.py and foundry/__init__.pyi alongside the reported missing imports, then determine why those dependencies are unavailable. Done means the lower scenario passes pyright and the dependency upper-bound validation runs.
