#273 ci: retire changelog-refresh cron, release-plz is the single changelog writer

[RAprogramm]

Closes #273

Two automations were writing to CHANGELOG.md: the weekly changelog-refresh.yml cron (git-cliff regenerating ## [Unreleased] via a GITHUB_TOKEN PR that never gets CI) and release-plz (release PR with the version bump and a curated ## [x.y.z] section from the same commits). The cron added nothing the release PR does not already show and left a duplicated ### CI block in [0.12.5].

Following the single release-PR model:

• delete .github/workflows/changelog-refresh.yml
• update the Changelog job comment in ci.yml (the run-summary preview stays; it is read-only)
• remove the duplicated cron-generated block from the [0.12.5] section

The empty ## [Unreleased] anchor stays as Keep a Changelog recommends; release-plz inserts new versions beneath it. #256 will be closed without merging once this lands.

Verified locally: actionlint, zizmor (no new findings), git-cliff still renders the Unreleased preview.

Summary by CodeRabbit

• Chores
  • Removed the automated weekly changelog refresh workflow.
