docs: reorganize docs — archive outdated, create brainstorming folder

- Create docs/brainstorming/ with 5 discussion records (Mar 16 - Apr 7)
- Archive ~30 outdated audit reports (V5-V11) to docs/archive/old-audits/
- Archive superseded analysis docs to docs/archive/old-analysis/
- Archive completed session plans to docs/archive/old-plans/
- Archive old test reports/validations to respective archive folders
- Remove empty directories left after moves
- Keep current docs: TRUTH.md, feature docs, deployment, knowledge-base, superpowers
