Adding New Tools

1. Create a new file in src/jons_mcp_pushover/tools/ or add to an existing file
2. Write an async function with type hints and a docstring:

   async def my_tool(param: str) -> str:
       """Brief description for the MCP tool listing.
   
       Args:
           param: What this parameter does.
   
       Returns:
           What the tool returns.
       """
       return f"Result: {param}"
   

3. Export from src/jons_mcp_pushover/tools/__init__.py
4. Register in server.py with mcp.tool(my_tool)
