Add the audit chain verifier

Implemented proto::ChainVerifier as a pure line-holding state machine: each line is judged only once the next has arrived, so a Recovery record can mark the line before it not-a-record. Adds ChainFailure, TornTail, ChainReport, Location and ChainVerifier, wired through lib.rs and the matching re-export in audit.rs. 13 chain tests pass; make gate prints gate: ok. Implemented-By: OpenCode session (model recorded in docs/implementer-log.md)
