 * that pulls in server-only code, the dead code elimination won't remove
 * that import because it sees the type as still referencing it.
 *
 * This function removes:
 * - `export type Foo = ...`
 * - `export interface Foo { ... }`
 * - `export type { Foo } from './module.js'`
 * - `export type * from './module.js'`
 * - Type specifiers in mixed exports: `export { value, type Foo }` -> `export { value }`
 * - `import type { Foo } from './module.js'`
 * - Type specifiers in mixed imports: `import { value, type Foo } from './module.js'` -> `import { value }`
 *
 * Note: Non-exported type/interface declarations are preserved as they may be
 * used as type annotations within the code.
