Prose rewrapping and table reflow from a project-wide markdown pass;
no content changes. Also reverts two formatter mistakes: restores
MD5(password) in dc3-web/AGENTS.md and drops spurious spaces after
CJK punctuation in README.zh.md / README.ja.md.
Covers root guides (AGENTS/CONTRIBUTING/SECURITY/README.*), module
READMEs across dc3-api/center/common/driver/e2e/gateway, the nginx
guide, dc3/doc/{README,TITLE}.md, and dc3-web docs.
The release-note source TITLE.md still carried outdated wording
("project development", "device integration and management") and
omitted the "AI-ready" positioning that README.md and the four
localized READMEs (zh/ja/vi) all promote as a core value proposition.
docker-ci.yml inlines this file into the GitHub Release body, so the
inconsistency surfaces every time we cut a release.
Realign the second paragraph with README.md:16-19 while keeping the
${SERVICE_VERSION} placeholder and the relative architecture image
path so docker-ci.yml's perl-based assembly continues to work.
