Pull request overview
This PR raises the minimum supported Python version for the Python SDK to 3.11 and modernizes type annotations across the Python package and test harness to use Python 3.10+ syntax, aligning linting and CI with the new baseline.
Changes:
- Bump Python package minimum version to
>=3.11and update Ruff target version accordingly. - Modernize type hints across Python sources/tests to use
X | None, built-in generics (list[...],dict[...]), and stdlibtyping.NotRequired. - Expand GitHub Actions Python SDK test workflow to run across a Python-version matrix.

I don't think those test failures are because of my PR. |

Update generated files for Python and Go SDKs to include new agent API types, compaction result types, and new session event types (assistant.streaming_delta, session.task_complete). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Run gofmt on go/rpc/generated_rpc.go and go/generated_session_events.go to fix spaces→tabs formatting that caused the Codegen Check to fail. - Fix test_resume_session_forwards_client_name to return a mock response for session.resume instead of forwarding to the real CLI, which requires the COPILOT_HMAC_KEY secret unavailable to fork PRs.

Python 3.10 gives us nicer type hint syntax and 3.11 gives us exception groups which will be used in the future. Along the way, expand the test matrix for Python versions in CI.
