refactor: restructure entire repo from v0-v9 to s01-s11 learning sessions

- Rewrite all Python agents (s01-s11 + s_full) with educational focus
- Rewrite all TypeScript agents for browser execution
- Consolidate Phase 4 teams from 5 sessions (s09-s13) to 3 (s09-s11)
  - s09: Team Messaging (spawn + inbox + broadcast)
  - s10: Team Protocols (shutdown + plan approval)
  - s11: Autonomous Agent (idle cycle + auto-claiming)
- Add 110 Vitest tests across 12 test files
- Rewrite all 11 session docs with ASCII diagrams
- Update web platform: inspector, simulator, playground
- Add GitHub Actions CI (typecheck + test + build)
- Remove old v* files, Chinese/Japanese articles, old Python tests
- Clean up unused design docs and assets

All verified: tsc 0 errors, 110 tests passing, build succeeds (84 pages)
