Concurrency Note Hidden in Non-Default Steering Modes

The concurrency note shown in the tool-use activity header is now gated on both the subscription tier and the steering mode. Previously it was only hidden for Pro-tier accounts. Now it also requires x3() === "default" — meaning no_nudges and counter_steer users no longer see the concurrency badge regardless of tier.

Evidence

showConcurrencyNote: oa() !== "pro" && x3() === "default" in tool event construction

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
