System.Reflection.Emit is blocked on arm64 simulators due to W^X — this is
what NSubstitute/Castle.DynamicProxy needs:
https://learn.microsoft.com/en-us/dotnet/maui/macios/interpreter

The Mono interpreter bypasses this by interpreting emitted IL instead of
generating native code. Sentry.Maui.Device.TestApp.csproj already has
<UseInterpreter>true</UseInterpreter> for Release, and the build already
passes EnableAot=false. So the two workarounds are redundant — either x64
via Rosetta OR the interpreter alone should suffice. Switching to
iossimulator-arm64 should work with the current build settings.

mlaunch (inside xharness) checks if simulator watchdogs are disabled
before launching an app. If they aren't, it shuts down the simulator,
writes plist files, then reboots — this sequence is flaky on CI, often
leaving the simulator stuck in a Shutdown state with:
  "Unable to lookup in current state: Shutdown"

Root cause was found by decompiling mlaunch with ilspycmd (it ships as
a compiled DLL in the xharness NuGet). It checks two plists under the
simulator's data directory:
  ~/Library/Developer/CoreSimulator/Devices/$UDID/data/Library/Preferences/
    - com.apple.springboard.plist
    - com.apple.frontboard.plist

All 6 FBLaunchWatchdog* keys must be >= 100, otherwise mlaunch shuts
down the sim to write them and reboots — which races on CI.

Fix: pre-write both plists with the 6 keys set to 100 before booting
the simulator ourselves. mlaunch then sees watchdogs already disabled
and the sim already booted, skipping its entire shutdown/reboot dance.
