PR Summary

Low Risk
Version and changelog-only release metadata with no library or runtime code changes in this PR.

Overview
Release 1.20.1 — bumps @version in mix.exs from 1.20.0 to 1.20.1 and adds the matching 1.20.1 section at the top of CHANGELOG.md (dated 2026-06-06).

The changelog entry records the only user-facing note for this patch: CI release workflow now uses OTP 28.5 ([#888]); that fix is not part of this diff—this PR is the automated Release Please cut for that change.
