Loop Governor: transforms scorecard-compound governor signals into loop control. Maps HALT/CONSOLIDATE/CONTINUE to loop-compatible halt decisions. Designed to be the feedback node in a looped chain — it reads the compound verdict and decides whether to keep iterating.

## Agent metadata

- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown
