`openclaw nodes run` always timed out after 35s with "gateway timeout
after 35000ms" even though `openclaw nodes invoke system.run` worked
instantly on the same node.
Root cause: the CLI's default --timeout of 35s was used as the WebSocket
transport timeout for exec.approval.request, but the gateway-side
handler waits up to 120s for user approval — so the transport was always
killed 85s too early.
Fix: override opts.timeout for the approval call to
Math.max(parseTimeoutMs(opts.timeout) ?? 0, approvalTimeoutMs + 10_000)
(130s by default), ensuring the transport outlasts the approval wait
while still honoring any larger user-supplied --timeout.
TypeBox Type.Optional(Type.String()) accepts string|undefined but NOT null.
Discord exec was failing with 'resolvedPath must be string' because callers
passed null explicitly. Web UI worked because it skipped the approval request.
Fixes exec approval validation error in Discord-triggered sessions.
