fix: advance supplied promotion readiness state

[ozand]

Summary

Fixes #461.

The live eeepc runtime produced a contradictory promotion candidate: readiness inputs were supplied (missing_inputs=[], provenance_complete=true, readiness_blocker.state=ready_for_policy_review) but the coordinator rewrote the durable promotion record back to not_ready_for_policy_review / blocked_not_ready.

This change makes the runtime writer preserve the supplied-readiness state consistently:

• if supply_missing_promotion_readiness_inputs() returns ready_for_policy_review, persist top-level review_status and decision as ready_for_policy_review
• keep decision_record=pending_operator_review_packet and accepted_record=null
• set governance_packet.review_packet_status=pending_operator_review
• teach runtime-state replay to classify ready_for_policy_review as a pending review state rather than blocked/not_accepted

Root cause

nanobot/runtime/coordinator.py called supply_missing_promotion_readiness_inputs(), but the surrounding not-ready branch then clobbered the ready result with hardcoded blocked values:

• decision_record=blocked_not_ready
• accepted_record=not_created_not_ready
• governance_packet.review_packet_status=blocked_not_ready
• stale top-level report/outbox review_status / decision

Test plan

RED before fix:

• python3 -m pytest tests/test_runtime_coordinator.py::test_cycle_promotes_supplied_readiness_inputs_to_ready_for_policy_review -q
  • failed because report["review_status"] stayed not_ready_for_policy_review
• python3 -m pytest tests/test_runtime_coordinator.py::test_load_runtime_state_classifies_ready_for_policy_review_as_pending_review -q
  • failed because replay state was blocked
