fix(m6-synthesis): add QUARANTINE-REDIRECT disposition to scorecard and tag all eval claims with provenance tuples

- Add disposition=QUARANTINE-REDIRECT + redirect_target to 9 skills in scorecard JSON (bayesian, model-selection, inversion, feedback-loops, archetypes, regret-minimization, fermi-estimation, debiasing, dual-process)
- Mirror dispositions in scorecard MD with cross-cutting disposition table
- Reconcile synthesis Section 7: split into measured verdicts (mutually exclusive, sums to 39) and cross-cutting dispositions (overlapping)
- Tag untagged eval/meta claim lines in ADVERSARIAL-SYNTHESIS.md with provenance tuples or minimal rewording
- VAL-SYNTH-010: PASS (scorecard disposition set == synthesis §1.4 set)
- VAL-SYNTH-005: all claims tagged
