perf: enhance TerserPlugin configuration for optimized compression and mangling (#65)

- Improved TerserPlugin compression by enabling `arguments` compression and increasing `passes` to 3 for better code optimization.
- Enabled `toplevel` mangling to reduce file size by optimizing top-level scope variables.
- Added `nameCache` to ensure consistent mangling between builds, improving cache performance.
- Maintained `sourceMap` support for easier debugging of minified code.
