Prepare durable extension RC package versions

[Chris Gillum (cgillum)]

Why

Package publishing is moving from microsoft/agent-framework to this repository. The versions originally copied during extraction have already been published and are immutable, so this repository needs the next ordered prerelease versions before its first deployment.

What

Promote both .NET packages to 1.16.0-rc1 and both Python packages to 1.0.0rc1. Keep the Azure Functions Python package coupled to the matching Durable Task RC, and align release metadata, changelogs, lock data, and the NuGet package-validation baseline with the latest published preview.

Compatibility

Package IDs and Python distribution names remain unchanged. These RC versions sort after the existing 1.16.0-preview.260730.1 NuGet packages and 1.0.0b260721 PyPI packages, preserving the established version line during the repository handoff.

Reviewer focus

Please verify the RC lifecycle choice, the cross-package Python dependency floor, and the use of 1.16.0-preview.260730.1 as the initial NuGet compatibility baseline.
