Skip common.ai provider from Airflow 3.0-3.2 CI compatibility tests

[rjgoyln]

Summary

Compat 3.0.6, Compat 3.1.8, and Compat 3.2.2 have been failing on main since 2026-09-04, all in providers/common/ai:

• cannot import name 'EventSource' from 'httpx2'
• FastMCP client support is not installed

The issue is caused by the old frozen constraints used by these jobs. common.ai requires pydantic-ai-slim>=2.0.0, but the 3.0-3.2 constraint sets pin incompatible dependency versions. Installing today's provider wheels with --providers-skip-constraints therefore creates a mixed environment that fails when the provider is imported.

Compat 3.3.1 passes, and 2.11.1 already skips this provider.

We should not raise the provider's apache-airflow floor: Airflow 3.0-3.2 do not impose upper bounds on the relevant dependencies, so common.ai still supports those releases outside the frozen constraints.

The prov:LowestDeps failures in the same canary are an unrelated ibm.mq pre-extras download flake, addressed separately in #71544.

IIUC, adding common.ai to remove-providers means these three jobs stop running the provider entirely, not just the failing MCP tests. The workflow deletes the wheel before installing and passes the same list as --skip-providers, which breeze turns into --ignore=providers/common/ai/tests.

#72581 pin devel dependencies to uv.lock, so it doesn't need to skip common.ai provider. WDYT?

Thanks! I checked #72581, and I agree that approach is better. It addresses the dependency issue without having to skip common.ai, so I’ll close this PR.
