refactor: Iteration 1 → 2 repo cleanup

Remove all Iteration 1 artifacts in preparation for Iteration 2:

- knowledge/ (26 docs): All content distilled into 7 Obsidian vault
  documents (Datenmodell v2.2, Technische Dok v2.0, Design-System,
  Visualisierungen, Entscheidungen, Iteration 1 Learnings, Project
  Overview v3.0)
- docs/ (47 files): Iteration 1 frontend (HTML, CSS, JS, view data).
  Will be regenerated in Iteration 2 with current data.
- One-off analysis scripts (analyze_archive*.py, create_signature_index.py)
- Derived data (m3gim.jsonld, view JSONs, reports)
- Iteration 1 config (.eslintrc.cjs, .prettierrc, IMPLEMENTATION-SUMMARY.md)

Retained: scripts/ (pipeline), .github/workflows/, package.json,
vite.config.js, .gitignore

Documents as Source of Truth, Code as Disposable Artifact.
