Helper macro to declare a plugin with automatic version management

Example

use mcp_plugin_api::*;

// Minimal (no configuration, no init)
declare_plugin! {
    list_tools: my_list_tools,
    execute_tool: my_execute_tool,
    free_string: my_free_string
}

// With configuration
declare_plugin! {
    list_tools: my_list_tools,
    execute_tool: my_execute_tool,
    free_string: my_free_string,
    configure: my_configure
}

// With configuration and init
declare_plugin! {
    list_tools: my_list_tools,
    execute_tool: my_execute_tool,
    free_string: my_free_string,
    configure: my_configure,
    init: my_init
