Generator: pilot analysis and fixes; G0002-G0021 tasks; handover notes merged

- Static bundle checks (name length, seed type, reserved words, contract test classes,
  testclasses_file), local abaplint parser check before SAP, max_tokens, robust JSON parse
- Runner: G2 for CDS views with parameters, contract_check detail in report
- G0020 and G0013 fixed by review and revalidated (oracle 100, null 0)
- Pilot results in docs/faz1-tasarim.md 11e; handover notes merged into CLAUDE.md and docs
