  The `list_tools` MCP tool handler. Registered via `@mcp.tool()` decorator. Returns a list of all available tools by inspecting the MCP server's internal tools registry (trying mcp._tools, mcp.tools(), or mcp.registered_tools). No input parameters required.

  Registration of the `list_tools` tool using the FastMCP `@mcp.tool()` decorator, which also infers the input schema from the function signature (empty parameters).
