- PR #99332: fix(memory): cap successful writes per turn to stop success-only mutation loops

These items address a bug where successful memory write operations could bypass loop guards, causing repeated or destructive mutations. The fixes introduce per-turn limits on memory writes to prevent runaway mutation cycles.

## TL;DR
