feat(gates): wire GATE 0 into the four orchestrator skill restatements

The include is authoritative, but feat/bugfix/ship-feature/init-project
each restate the verify loop inline — an orchestrator following the
restatement alone would have skipped the floor. Each now carries the
GATE 0 bullet ahead of GATE 1 (4 new structure locks, flip-tested).
The contract-interview weight table stops promising a hotfix oracle
nothing executes: hotfix runs no floor, the hotfixer runs the suite
itself. CHANGELOG extended with the wiring + the RED result.
