Python: [Breaking] Upgrade to azure-ai-projects 2.0+

[eavanvalkenburg]

Motivation and Context

This change completes the Python move to the azure-ai-projects 2.0 GA surface. It replaces the prior beta dependency pin and removes compatibility behavior that no longer matches the supported SDK baseline, while keeping preview opt-in available through the allow_preview flag supported by the 2.0 client.

Description

• Update the Python core dependency bound for azure-ai-projects to >=2.0.0,<3.0 and refresh uv.lock.
• Align Azure AI integrations with the GA SDK model surface by using the 2.0 type names for code interpreter containers and text response formats.
• Remove compatibility/feature-detection paths that were added for mixed SDK behavior and assume the supported 2.0 client surface directly.
• Remove unsupported foundry_features passthrough from Azure AI agent creation, since the 2.0 create_version API does not expose that parameter.
• Preserve preview opt-in where it is actually supported by wiring allow_preview through the Azure AI client, responses client, and Foundry memory provider creation paths.
• Update Azure AI tests and sample/docs to reflect the supported SDK behavior, and add Python contributor guidance in python/AGENTS.md for PR descriptions to follow the repository template.
• Include small repo-hook-driven cleanup changes in touched Python files.

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the Contribution Guidelines
• All unit tests pass, and I have added new tests where possible
• Is this a breaking change? If yes, add "[BREAKING]" prefix to the title of the PR.

Pull request overview

Updates the Python Azure AI integration to require azure-ai-projects GA (2.0+) and removes/updates code paths that existed only for pre-2.0 SDK compatibility, aligning core + Azure AI package code and samples with the v2 API surface.

Changes:

• Bump azure-ai-projects dependency constraint to >=2.0.0,<3.0 (and refresh the lockfile to GA).
• Update Azure AI client/provider code to support allow_preview on internally-created AIProjectClient and gate preview-only agent creation behavior accordingly.
• Remove/replace pre-2.0 model/tool types (e.g., Code Interpreter and text response format types) and adjust tests/samples.
