OpenClaw's config env vars allowed startup env injection into service runtime

Summary

OpenClaw allowed dangerous process-control environment variables from env.vars (for example NODE_OPTIONS, LD_*, DYLD_*) to flow into gateway service runtime environments, enabling startup-time code execution in the OpenClaw process context.

Details

collectConfigEnvVars() accepted unfiltered keys from config and those values were merged into the daemon install environment in buildGatewayInstallPlan(). Before the fix, startup-control variables were not blocked in this path.
