Bryan Helmkamp cab25a3e7e Add failure signatures and circuit breakers for deterministic failure cycle detection ... Introduces reason normalization (strip variable data like line numbers, hex hashes), composite failure signatures (node_id|class|normalized_reason), and circuit breakers that track signature counts to abort when the same deterministic failure repeats beyond a configurable limit (default 3). Key additions: - normalize_failure_reason() strips hex, digits, whitespace for stable grouping - FailureSignature type with handler-provided hint priority - FailureClass::is_signature_tracked() (deterministic + structural only) - Graph-level loop_restart_signature_limit attribute - LoopState struct bundling node_visits + signature maps through run_internal - Loop failure circuit breaker (same node repeating) - Restart failure circuit breaker (across loop_restart edges) - Checkpoint persistence for both signature maps with backward compat - 18 e2e integration tests covering all circuit breaker scenarios Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>		2026-03-01 18:03:09 -05:00
