Add state helper and refresh specifier briefing

Add state.sh to print each role branch HEAD and the main-checkout status.
Update the briefing to use the single tmp/aps checkout, note daemon
self-healing, and point merge verification at verify.sh and the architect's
verification record.

By specifier.
