fix(node-host): fail closed on ruby approval preload flags

CHANGELOG.md

@@ -43,6 +43,7 @@ Docs: https://docs.openclaw.ai
 - Security/agent: reject public spawned-run lineage fields and keep workspace inheritance on the internal spawned-session path so external `agent` callers can no longer override the gateway workspace boundary. (`GHSA-2rqg-gjgv-84jm`)(#43801) Thanks @tdjackey and @vincentkoc.
 - Security/session_status: enforce sandbox session-tree visibility and shared agent-to-agent access guards before reading or mutating target session state, so sandboxed subagents can no longer inspect parent session metadata or write parent model overrides via `session_status`. (`GHSA-wcxr-59v9-rxr8`)(#43754) Thanks @tdjackey and @vincentkoc.
 - Security/agent tools: mark `nodes` as explicitly owner-only and document/test that `canvas` remains a shared trusted-operator surface unless a real boundary bypass exists.
+- Security/exec approvals: fail closed for Ruby approval flows that use `-r`, `--require`, or `-I` so approval-backed commands no longer bind only the main script while extra local code-loading flags remain outside the reviewed file snapshot.
 - Security/device pairing: cap issued and verified device-token scopes to each paired device's approved scope baseline so stale or overbroad tokens cannot exceed approved access. (`GHSA-2pwv-x786-56f8`)(#43686) Thanks @tdjackey and @vincentkoc.
 - Models/secrets: enforce source-managed SecretRef markers in generated `models.json` so runtime-resolved provider secrets are not persisted when runtime projection is skipped. (#43759) Thanks @joshavant.
 - Security/WebSocket preauth: shorten unauthenticated handshake retention and reject oversized pre-auth frames before application-layer parsing to reduce pre-pairing exposure on unsupported public deployments. (`GHSA-jv4g-m82p-2j93`)(#44089) (`GHSA-xwx2-ppv2-wx98`)(#44089) Thanks @ez-lbz and @vincentkoc.
