Subject: [PATCH] fix(openclaw): add comment clarifying proc.exited race
 condition avoidance

cubic identified potential race condition where Bun's proc.exitCode
may be null immediately after stdout closes. Added clarifying
comment that await proc.exited ensures exitCode is set before
checking.

fixes: cubic review on PR #2620
