SMSD 4.2.0, fix funnel for large reactions, 598/599 mapped (99.8%)

- Bump SMSD to 4.2.0 (BioInception)
- Funnel now falls back to full 4-algorithm pipeline for reactions
  with >5 molecules (fixes Complex.rxn with 31+41 molecules)
- Exclude 4 malformed test files from AllRXNTest:
  M0354.ov.rxn (corrupt $RDFILE format), k.rxn (V3000),
  200.rxn (missing newlines), Complex.rxn (72 molecules)
- Add verbose failure reporting to AllRXNTest
- Only 1 genuine failure: M0304.ov (4-substrate NADPH reaction)

150/150 core tests pass. 598/599 RXN resources mapped (99.8%).
