[internal] remove `dist/` from versioning, add needed release steps

Versioning dist adds unneeded changes for contributor PRs. Ideally dist should not be versioned and instead only as part of npm publish or a release process.

todo

• add to .gitignore
• modify Gruntfile.js with publish task, incorporate into other steps

Agree, it's also error prone to have 2 source of truth.
it's already part of 'build' steps and 'publish' should do that as pre-req.
