Auto-set package version from release tag

[milldr]

Summary

• Publish workflow now extracts the version from the release tag and sets it in package.json before npm publish, so the repo no longer needs manual version bumps to publish correctly
• Release Drafter default changed from patch to minor, and added enhancement/bug labels to version-resolver so changelog categories correctly map to version bumps
• Bumped package.json to 0.2.0
• Created GitHub labels (major, minor, patch, feature, fix, bugfix, no release, docs) and cleaned up the failed v0.1.1 release

Test plan

• Merge this PR, verify Release Drafter creates a draft targeting v0.2.0
• Publish the draft release, verify npm view @milldr/crono version returns 0.2.0
