Reframe roadmap around the gate-first focus loop

Make the OS-level "gate → plan → work → reflect → gate" loop the explicit
destination. Promote the deferred AI reviewer into the loop as M7 (Reflection),
and reframe enforcement as M8 (Enforcement & gate) building toward the Guard
checking for a declared intention before the machine is usable — kept as the
last, heaviest milestone.
