🚀 Benchmark Results

Compared to main @​ 130e803f: memory to the latest run, time to the median of the last 10 runs, as the runners differ in speed. A relative change marks when Mockolate gets more than 15% faster or slower relative to Imposter and TUnitMocks: 🔴 / 🟢 against both of them, 🔸 / 🔹 against only one.

fix: reference Microsoft.Bcl.AsyncInterfaces for the net8.0 tests
9535b2c 
TUnit 1.83 no longer ships a net8.0 build, so net8.0 uses its netstandard2.0 build, which references Microsoft.Bcl.AsyncInterfaces without declaring the package; the test host then fails to start.
