Add AES-256-GCM local encrypted secrets provider with auto-generated master key, stub providers for AWS/GCP/Vault, and a secrets service that normalizes adapter configs (converting sensitive inline values to secret refs in strict mode) and resolves secret refs back to plain values at runtime. Extract redaction utilities from agent routes into shared module. Redact sensitive values in activity logs, config revisions, and approval payloads. Block rollback of revisions containing redacted secrets. Filter hidden issues from list queries. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
