+ * Get all top-level identifiers that should be preserved when exported in TypeScript.
+ *
+ * Examples:
+ * - If an identifier is declared as `const x`, then `export {x}` should be preserved.
+ * - If it's declared as `type x`, then `export {x}` should be removed.
+ * - If it's declared as both `const x` and `type x`, then the export should be preserved.
+ * - Classes and enums should be preserved (even though they also introduce types).
+ * - Imported identifiers should be preserved since we don't have enough information to
+ *   rule them out. --isolatedModules disallows re-exports, which catches errors here.
