Refactor Vite configuration and remove audio worklet plugin for improved build performance

Commit notes

This commit updates the Vite configuration to replace Terser with ESBuild for faster minification and optimization in production builds. The audioWorkletPlugin has been removed, streamlining the build process and enhancing performance. Additionally, the WORKLET_PROTECTION.md documentation is updated to reflect the new ESBuild setup and its benefits for protecting intellectual property in the sequencer processor worklet. Unused dependencies have also been cleaned up from package.json.
