OpenClaw safeBins stdin-only bypass via sort output and recursive grep flags
Summary
tools.exec.safeBins could be bypassed for filesystem access when sort output flags (-o / --output) or recursive grep flags were allowed through safe-bin execution paths.

>= 2026.2.19 - Latest published version at triage time:
