fix(runtime): production controller install never wired OnInterfaceText — the jump-in-air silence

Round-3 probe evidence pinpointed it: '[jump] ReportJumpRefusal
result=NotGrounded hasCallback=False' — the edge detection, OnWalkable
clearing, and refusal dispatch all worked; the callback was null because
CommitRuntimeOwnedController (the C3c production publication path) writes
_controller directly and never applied _onInterfaceText the way the
internal setter does. Two install paths, one wired. Regression test pins
the commit path.

Runtime tests 1,323/0.
