Simplify spec: remove sub, move compensation to ext, add RFC 8126

Browse Source 
Restore from pre-linter base (898b0f8) and re-apply targeted
changes to avoid unintended structural rewrites:

- Remove sub claim (always equals iss, adds no information)
- Move compensation_required and compensation_reason to ext keys
- Trim witness attestation section to concise guidance
- Fix ledger-mandatory language in verification step 15 and
  minimal implementation step 5
- Add RFC 8126 to normative references

Policy evaluation claims (pol, pol_decision, pol_enforcer) remain
as registered JWT claims in this spec.
