The new stack size is 256kb in order to compromise with llama.cpp's aggressive use of stack memory, which can't be easily patched. This change disables the dynamic alloca() and VLA warnings for now, plus frame sizes for individual functions may be <=50% of the stack size This only applies to code in the cosmo monorepo. Open source builds should already be using an 8mb stack by default, like everyone else
