Pull request overview

This PR removes the previously composed jupyter-mcp-server integration and refocuses earthdata-mcp-server on Earthdata-only capabilities, adding explicit download “modes” and updating docs/examples accordingly.

Changes:

• Removed jupyter-mcp-server dependency and all runtime/notebook composition logic from the server/CLI.
• Reworked download_earth_data_granules into manifest / download / script modes and documented the intended composition pattern via mcp-compose.
• Updated README/docs/examples/tests to reflect the Earthdata-only scope.
