Move PRD, design specs, architecture docs, and TDD from .autoflow/
(personal/per-branch layer) to docs/autoflow/ (shared layer that
goes into git) per the new Autoflow workspace layout.
Files moved:
- 02-prd/PRD.md
- 03-design/design-review.md
- 03-design/user-flow-cross-system.md
- 04-architecture/TDD.md
- 04-architecture/design-doc.md
- 04-architecture/security.md
The originals were never tracked, so git mv reduced to a filesystem
rename with no history to preserve. .autoflow/ remains for personal
notes (progress.md, review reports, testing logs).
