Refresh Band 1 audit note hygiene

[williamclay8]

Summary

• refresh stale Band 1 remediation note Lumi footers after the 995b24b commit/push/live website status evidence
• preserve explicit fail-closed wording for on-chain spend/verifier programs, TAG5/TAG6, SBF/live lineage, and production privacy

Verification

• npm run privacy-audit:tracker-check
• npm run private-pool-v2:live-anonymity-set-probe-check
• npm run truth:privacy-claim-gate

Truth boundary

This is docs-only hygiene. It does not deploy verifier programs, register TAG5 keys, provide SBF/live lineage, lift privacy claims, or change production readiness.
