refactor: move type parameter from measureCtx outer to inner function

- Move generic type parameter <T> from measureCtx function to the returned function
- Update MeasureOptions parameter to use MeasureOptions<T> for proper typing
- Remove type casts in profiler measure and measureAsync methods
- Fix measureAsync to properly await work function before calling success

This change allows the type system to properly infer the result type T
throughout the measurement chain without requiring type assertions.
