Manage dist folder and conditional npm publishing

[dyatko]

Remove the committed dist folder and implement CI/CD to verify builds on PRs and automate npm publishing on master.

This change significantly reduces repository size, cleans up git history by removing build artifacts, and streamlines the release process by automatically publishing new versions to npm with provenance when merged to master. The package version has also been bumped to 2.0.0.
