fix: regenerate uv.lock files for agent-framework 1.1.1

The Dockerfile uses 'uv sync --frozen' which reads from uv.lock, not
pyproject.toml. The lock files were still pinned to the old beta
versions (1.0.0b260107/1.0.0b260127), causing the Docker build to
install the old beta despite pyproject.toml specifying 1.1.1.

Regenerated both lock files to resolve agent-framework 1.1.1 with
agent-framework-openai 1.1.1 and agent-framework-core 1.1.1.
