v0.12.2

• Metric Functions: Metrics now support built-in functions such as ratio(A, B) and sum(A, B, C, ...), enabling more expressive and reusable formulas (see the documentation).
• Optimized Compile-time Event Injection: The generated runtime event registration class is now only created if it does not already exist, reducing unnecessary recompilation.
• Improved Live Event Accuracy: Live event values now account for partial runtime durations via time scaling, improving accuracy when counters were not active for the full measurement window.
