Conversation
- Converts the `while(true)` loop to a `for` loop to allow the JIT compiler to elide bounds checks. - Eliminates `Math.Min` and redundant branch checks. - Removes unnecessary `ulong` to `int` casting. Co-authored-by: manupawickramasinghe <73810867+manupawickramasinghe@users.noreply.github.com>

💡 What
Optimized the
TryValidateRangeloop by replacing the explicitwhile(true)iteration with a tighterforloop over the memory regions span. This eliminatesMath.Mincalls, redundantremaining == 0branching, and per-iterationulongtointcasts.🎯 Subsystem & Bottleneck

Math.Mincalculations and reduced branches by removing thewhile(true)bounds validation step, enabling standard array/span JIT bounds-check elision via standardforloop indexing.🔬 Verification Checklist
