//! TypeScript type generation using ts-rs
//!
//! This module collects all API types with `#[derive(TS)]` and generates
//! TypeScript declarations that are combined with the proc macro output.
//! The generated TypeScript is validated and formatted using oxc.
//!
//! Types are automatically collected based on `JSEDITORAPI_REFERENCED_TYPES`
//! from the proc macro, so when you add a new type to method signatures,
//! it will automatically be included if it has `#[derive(TS)]`.
