The decoy suite is a gate of the full run (R-1116); no code change

controller/scripts/test_gate_decoys.py is now controller_gates.py's `gate-decoys` row: blocking, full run only
(~22 s, 53 cases, and it edits real files in the tree for a moment, so never the hook). Declared in its own
COVERS; test_controller_gates.py pins it. Red-proved: debug-routes/comment flipped to expect accept ->
CONVICTED: gate-decoys; restored, green. gates.md's "--fast is all of them" corrected.
