v0.13.99.1-patch: Kernel Deadlock & Multichannel (5.1) Stability Fixes

full disclosure: I am a node.js dev with zero C++ or windows driver experience. SAR was hard-freezing the Windows audio service and blue-screening my entire PC whenever I scaled up multiple 5.1 surround feeds for Speedromizer.

i fed the source code into an LLM (gemini 3.8), it tracked down memory corruption bugs and kernel race conditions from 2015, and patched them. peak "i have no idea what i'm doing, but it 100% works on my machine" energy. tested under live 5.1 streaming loads on my machine. do i need to say this again, it works ON MY MACHINE and i give zero guarantees this works on anyone elses lol

follow the source repo's instructions on test signing/etc.
