draft-release-notes.py: add `build` and `ci` to _PREFIX_HINT so commits
using those Conventional Commits prefixes get categorized correctly
instead of falling through to "other".
dist/kami.zip: rebuild via package-skill.sh so the archive picks up the
two new GitHub Actions workflows and scripts/draft-release-notes.py
(86 files, 4.4MB).
scripts/draft-release-notes.py emits a V1.4.0-shaped bilingual scaffold
(centered hero, English Changelog, 更新日志, footer) populated from
git log <range>. Default range is <latest tag>..HEAD; commits are listed
as numbered TODO bullets with a category hint comment so the author can
regroup them into 5-8 product-themed items before publishing.
AGENTS.md repository map adds the draft script, the test suite path,
and the two new GitHub Actions workflows. Commands list grows by one
draft-release-notes invocation example.
