Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request migrates the project's build system from TypeScript Compiler (TSC) to SWC, a significantly faster JavaScript/TypeScript compiler. The changes involve updating the build script in package.json, adding necessary SWC and Tsup dependencies, and introducing new configuration files for these tools. The primary goal is to enhance compilation performance and optimize the overall build process.

Highlights

• SWC Integration: The primary build script has been updated to use SWC (Speedy Web Compiler) instead of TypeScript Compiler (TSC), aiming for faster compilation times.
• New Build Tooling: New development dependencies, including @swc/cli, @swc/core, and tsup, have been added to facilitate the SWC-based build and bundling process.
• Configuration Files Added: A new .swcrc file has been introduced to configure SWC's compilation settings, and tsup.config.ts was added for bundling configurations.
• TypeScript Configuration Updates: The tsconfig.json file was modified to enable incremental compilation and remove the explicit include property, streamlining the TypeScript configuration.

Code Review

This pull request successfully migrates the build process from tsc to swc, which should improve build performance. However, I've identified a critical runtime error due to a missing import, a significant logic bug in error handling, and a potential tooling issue with the tsconfig.json that need to be addressed to ensure correctness and maintainability.

Closing as SWC doesn't do type checking.
