Agora Workbench v0.1.1

Added

• Trusted Publishing workflow for building validated release distributions and publishing them to PyPI.
• Pull request packaging checks and repeatable TestPyPI candidate deployments with clean-install smoke tests.
• agora-workbench-deploy init --target activity-ui for scaffolding the standalone monitoring service from the installed package.

Changed

• Excluded tests, bytecode, and cache artifacts from wheel and source distributions.
• Updated installation guidance to use the released PyPI package while identifying bundled examples that require a source checkout.
