ci: restore conventional-commit release notes with contributors

PR #136 replaced the custom release-notes.mjs script with
ncipollo/release-action's generateReleaseNotes, which relies on
PR labels that nobody applies — resulting in empty release notes.

Restore the script that parses conventional commit prefixes (feat,
fix, etc.) directly from git log, groups them into Features & Polish
/ Fixes / Misc buckets with collapsible details, and appends a
Contributors section with first-time contributor welcome.

Wire it into the publish-release job: preface + script output →
RELEASE_BODY.md, replacing generateReleaseNotes.
