//! 灵感类 AI 工具声明式注册(register_idea_tools 2 个:list + create 迁入)。
//!
//! 迁自 `tool_registry.rs::register_idea_tools`(原 2 个 list_ideas/create_idea),
//! 改用 `declare_tool!` 宏。
//!
//! 迁移策略(handler 逻辑零变更):
//! - handler body 逐字照搬原 `register_idea_tools` 内 async move 块(逻辑等价),
//!   仅闭包包装(`{ let db = db.clone(); Box::new(move |args| { let db = db.clone();
//!   Box::pin(async move { ... }) }) }`)改由 `declare_tool!` 宏生成。
//! - name/desc/schema/risk 与原手写定义逐字一致。
//! - 复用类型/常量:new_id/IdeaStatus/IdeaRecord/now_millis(各 pub(crate) 来源,与原同源) +
//!   MAX_LIST_RESULTS(super::tool_registry 单真相源)。
//!
//! 等价性验证:基线测试 `test_build_ai_tool_registry_baseline_tool_count` 仍断言 48 总量 +
//! 工具名集合稳定(防 rename / 漏注册)。
