Describe the bug

Regarding bun-plugin-dtsx: "0.21.17"

When I am having configuration like below

import { $ } from "bun";
import dts from "bun-plugin-dtsx";

const buildStart = performance.now();

const outdir = "./dist";

// Clean the output directory, equivalent to tsup's `clean: true`
await $`rm -rf ${outdir}`;

const result = await Bun.build({
  root: "./src",
  entrypoints: ["./src/index.ts"],
  outdir,
  format: "esm",
  splitting: false, // Matches tsup config
  sourcemap: "none", // Matches tsup config `sourcemap: false`
  minify: true, // Standard for production builds
  external: ["react", "react-dom"], // buFrom peerDependencies
  plugins: [
    dts(),
  ],
});

if (!result.success) {
  console.error("Build failed");
  for (const message of result.logs) {
    console.error(message);
  }
  process.exit(1);
}

const buildEnd = performance.now();

console.log("Builder completed.");
console.log(`Build time: ${buildEnd - buildStart} ms.`);

console.log("Build completed successfully.");
for (const output of result.outputs) {
  console.log(`  - ${output.path}`);
}

and index.ts file as

export * from "./props";
// export * from "./session";
// export * from "./types";
// export * from "./time";
// export * from "./lang";
// export * from "./locale";
// export * from "./hooks";
// export * from "./download";
// export * from "./expression";
// export * from "./id";
// export * from "./dom";
// export * from "./auth";
// export * from "./regex";
// export * from "./pipeline";
// export * from "./capability";
// export * from "./predicates";
// export * from "./compare";
// export * from "./url";
// export * from "./functools";
// export * from "./event-bus";
// export * from "./action";
// export * from "./data";

tsconfig.json:

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "display": "Standard Library",
  "extends": "@up/typescript-config/library.json",
  "compilerOptions": {
    "outDir": "./dist",
    "rootDir": "./src",
    "forceConsistentCasingInFileNames": true,
    "types": ["node"],
    "skipLibCheck": true
  },
  "include": ["src/**/*.ts", "src/**/*.tsx"],
  "exclude": ["node_modules", "src/**/*.test.ts", "src/**/*.data.ts", "dist"]
}

I see this:
Which included non-exported files and test file too which are already excluded in tsconfig.json

When using bun-plugin-dts library, it like giving one d.ts file

Reproduction

Screenshot attached.

I really want to use this library because of speed which is better than bun-plugin-dts
