Issue with the validation in jupyter_mcp_server/server.py
@mcp.tool()
async def insert_execute_code_cell(
cell_index: Annotated[int, Field(description="Index of the cell to insert and execute (0-based)", ge=0)]
This prevents the index from being set to -1 , which appends the cell to the bottom of the notebook.
-Changed ge=0 to ge=-1.
-Added unit test for appending code cell in test_tools
