refactor(diagrams): switch to raw GitHub URLs from axme-docs (#29)

Replace all local SVG copies with raw.githubusercontent.com URLs
pointing to the canonical source in axme-docs/docs/diagrams/.

- All diagram images now always reflect the latest version
- Removes 2-9 duplicate SVG files per repo
- No more stale copies when diagrams are updated in axme-docs
- The docs/diagrams/ directory is removed where it contained only SVGs

Diagrams source of truth: AxmeAI/axme-docs/docs/diagrams/

Made-with: Cursor
