Vickey 69e5fbe0ac docs: restructure documentation and archive engineering notes ...

Separate the public docs (how to understand, deploy, and use IoT DC3) from
engineering material (design drafts, analyses, roadmaps, legacy operation
screenshots):

- add an internal archive area with its own nav, grouping design,
  analysis, strategy, backlog, and legacy-operation sections
- migrate design, operation (data/device/driver/template), analyses, and
  todo notes into the archive, preserving history
- refresh public docs: README (en/zh/ja/vi), operation guides
  (agentic/concepts/data-commands/device-onboarding), architecture,
  development, guide, quickstart, and modules
- promote the project overview to README.ai.md at the repo root
