docs: reorganize project documentation (#15)

## Summary
- add a root README with project overview, setup, usage, architecture, security, and contribution guidance
- replace stale planning and requirement notes with current 1.0 project overview
- update architecture and hardware validation docs to match the implemented app
- remove obsolete UI branch notes and the old Java/XML AsyncTask example
- remove the superpowers documentation and move vendor ABSDK references into docs/vendor
- preserve vendor Markdown and XLS content byte-for-byte

## Verification
- Markdown relative links checked
- vendor files verified as 100% Git renames
- git diff --check passed
- no application tests run; documentation-only change
