Greptile Summary

This PR adds windowsHide: true to the two execFileAsync call sites in runExec and the spawn call in runCommandWithTimeout, suppressing the brief console flash seen when OpenClaw tools spawn child processes on Windows. The option is safely ignored on non-Windows platforms by Node.js. Tests cover all three execution paths: cmd.exe-wrapped .cmd shims, the direct execFile path, and npm shim spawns.

Confidence Score: 5/5

• Safe to merge — minimal, targeted change with full test coverage for all affected code paths.
• All three child-process launch paths now carry the option, the option is a no-op on non-Windows, and the new/updated tests assert the flag across wrapped, shimmed, and direct execution paths. No P0/P1 findings.
• No files require special attention.
