⚡ [performance improvement] Replace synchronous remove with async remove in bundle.ts

- Replaced `fs.removeSync` with `await fs.remove` in `compileHermesByteCode` and `copyDebugidForSentry` functions within `src/bundle.ts`.
- This change avoids blocking the event loop during I/O operations, making the codebase more efficient.
- Verified that the changes were correctly applied and the project remains stable.
