- PR #134869: fix(mcp): close the OAuth inner auth-flow generator in the owning task

A bug where the async_auth_flow bridge fails to call aclose() on the SDK's inner generator, causing context.lock to be poisoned across tasks and permanently stalling OAuth MCP servers. Members include a bug report and two related fix attempts addressing generator cleanup in the owning task.
