Summary: Adds a fail-closed emission gate for local backend telemetry probe results. Every LocalBackendProbeRecord now round-trips through the CR-118 local_backend_probe_record.v1 validator before the probe returns, renders, or writes it as an observation. The gate applies to reachable records and fail-closed probe observations. If record-contract validation fails, probe_local_backend raises ProbeInputError instead of producing a successful probe result. Scope boundaries: no new backend types, probe endpoints, model calls, routing integration, circuit breakers, degraded modes, ledger writes, or CLI behavior changes. Validation: focused local backend probe + CR-118 contract tests: 34 passed. Full Windows suite: 916 passed, 2 skipped. py_compile triage_core/local_backend_probe.py passed.
