Note

Low Risk
Low risk: this is a release metadata update (version/changelog) with no functional code changes in the diff; the only behavior-impact called out is the documented Node >=20 requirement.

Overview
Bumps the release from 1.1.0 to 1.2.0 by updating package.json and .release-please-manifest.json.

Updates CHANGELOG.md with the 1.2.0 entry, noting the minimum supported Node version is now >=20.
