xbzk	aaa0bcb9bf	[patcher, ro, settings] runtime tls patch (#4492 ) optimization and nuke toggle (#4502 ) (#4523 ) - [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md) - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- This is a follow up for the biomutant fix. By the time i knew it was shallow, coz i was running patchtext routine even for svc and modules, causing a routine which were needed to run 14 times to run 4000+ instead. Since some perf loss was reported in 30 sep nightly, and it caused ac3r to not boot, we had added a temp toggle, which is now being removed as optimizations + fix are in.
