Fixes #16622
z.number().int()changed in zod v4 & now adds a maximum constraint ofNumber.MAX_SAFE_INTEGER, which overflows llama.cpp's json schema -> grammar conversion logic.int64_tsaves the day!A separate issue is with large max values probably about to become more commonplace with that change in zod, we'll need to optimize the grammar generated. Will send separately.
