Conversation
_trip_budget is now idempotent per turn (TurnState.budget_tripped), so multiple StepBegins past max_steps_per_turn journal the breach exactly once instead of once per offending step. Tracks the trip task reference (self._trip_task) and cancels/clears it on the same teardown paths as the wall-clock watchdog.

What
P0 of the coder agent panel (spec, plan): the platform guards and generalized runner base that every later phase builds on.

Most-restrictive by construction: capabilities
false/false, every inbound approval/question request rejected with -32601 (golden-tested at runner and HTTP level), no respond endpoint exists. The approvals bridge is P1, gated behind the trust-store hardening.Tests
