feat(autofix): collapsed-Chinese bilingual takeover comments; fix ESLint regex-spaces

Every takeover-flow comment — engage ack, release ack, re-arm ack, and
the cap-pause notice — now follows the project convention: English
body plus Chinese collapsed under <details><summary>中文说明</summary>
(pinned at exactly four sites). Bodies are built via printf so no
workflow indentation leaks into the markdown: the previous literal
multi-line strings embedded 10 leading spaces, which would have
rendered the trailing marker comment as a visible code block.

Also fixes the CI failure at 1497a7e6f: three extraction regexes used
literal space runs, tripping ESLint no-regex-spaces — now {n}
quantifiers. Lesson applied: prettier alone is not the lint gate.

58/58 + 12/12.
