Pull Request Overview

This PR introduces a lightweight server implementation that wraps a Ume model for generating embeddings, along with associated tests and dependency configuration updates.

• Adds a new UmeServer class in src/lobster/server/_server.py that registers an embedding tool.
• Implements tests in tests/lobster/server/test__ume_server.py for validating the server’s behavior with various modalities and inputs.
• Updates the dependency configuration in pyproject.toml and adjusts notebook metadata in two notebooks.

• [nitpick] Test function names include 'mcp' even though the server class is named 'UmeServer'. Consider renaming them for consistency and clarity.

• Using assert_called_with in a loop only verifies the most recent call. Consider resetting the mock between iterations or using assert_has_calls with a list of expected calls to thoroughly validate every invocation.

very nice! could you please add README in src/server describing usage?
