Release/1198.0.0

[abretonc7s]

Explanation

Release @metamask/perps-controller 12.1.0. No other packages.

Minor bump. New public API:

• Optional PerpsPerformance.onControllerConstructed post-hydration hook
• PerpsTracer.setMeasurement overload that takes a trace ID
• PERPS_EVENT_PROPERTY.PREVIOUS_LEVERAGE (previous_leverage)

Also retargets market/user preload measurements onto their named traces and drops wallet addresses from user-preload trace data.

No breaking changes. Existing 3-arg setMeasurement callers and clients that omit the new hook keep compiling.

• feat(perps): add PREVIOUS_LEVERAGE to Perps analytics event properties #9881
