Synchronize the shortest runnable restart command into agent memory

Constraint: Limit this checkpoint to memory and handoff documentation only
Rejected: Keep the restart command only in README | New sessions should see the first verification command directly in AGENT memory too
Confidence: high
Scope-risk: narrow
Directive: Keep AGENT memory focused on restart-critical commands and avoid duplicating full workflow specs there
Tested: Rechecked 174 relative links across AGENT, changelog, and handoff docs
Not-tested: No code or training path executed in this memory-only checkpoint
