Hard batch G0022-G0026: 5/5 accepted; budget floor, CDS checks, mutation check

- generator: budget floor (2x oracle activations, 3x calls), static checks for CDS
  $parameters and UNION annotation
- harness/mutation.py: deterministic mutants of the reference; hidden tests must fail
- G0022 revalidated with harness fixes: oracle 100, null 0
- results in docs/faz1-tasarim.md 11f
