Code outside the router now reaches it only through the entry points
(registry, settings, health, select, apply, observe, register_plugin, retire)
or the endpoint methods; the outside-member allowlist shrinks from 139 to 45.
litellm/router.py no longer imports litellm.proxy: it asks the installed
RouterHost (litellm/router_host.py) for vertex pass-through credentials,
member auto-router authorization and auto-router prompt compression, and the
proxy installs its host on import. Call sites where a model name can be
missing keep the old answer instead of reaching an entry point with None.
* refactor(mcp): drop the experimental label from the MCP server and client paths
Move litellm/proxy/_experimental/mcp_server to litellm/proxy/mcp_server and litellm/experimental_mcp_client to litellm/mcp_client, with the mirrored tests moved under tests/unit/proxy/mcp_server and tests/unit/mcp_client. Both old packages stay as shims that warn with DeprecationWarning, re-export the new package's public names and alias every submodule in sys.modules so deep imports keep resolving to the same objects. The OpenAPI docs gate now puts the merge base's enterprise package on PYTHONPATH so its base counts do not mix the checked-out enterprise code with the base litellm tree

* ci(mcp): keep tests/unit/proxy/_experimental as a sharded root for the shim tests

* fix(mcp): alias namespace subpackages and bind attributes in the deprecated MCP shims
pkgutil.walk_packages skipped mcp_server/auth because it has no __init__.py, so old imports of litellm.proxy._experimental.mcp_server.auth.* failed, and sys.modules entries alone left litellm.experimental_mcp_client.tools unreachable as an attribute. Walk the package on disk and setattr each alias on its old parent.
