docs(release): align TITLE.md with main README description

The release-note source TITLE.md still carried outdated wording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.
