* fix: mark local/opencode as implemented in README matrix

* fix: update README agent/cloud counts and use claude.ai favicon

- Update README tagline: 10 agents/10 clouds/99 combos → 6/8/48 (accurate)
- Re-download claude icon from claude.ai/apple-touch-icon.png instead of
  Anthropic GitHub org avatar (62K vs 4.5K, higher quality source)
- Update assets/agents/.sources.json to reflect new claude icon source
