I've cherry picked this patch and confirmed it was caused by insufficient buffer capacity, which fixes #226.

This commit adds bounds checking to add_type and increase MAX_TYPES to 128, fixing memory corruption during stage-1 compilation when typedef count exceeds limit.
Summary by Bito
This pull request fixes a critical bug by increasing the maximum number of types from 64 to 128, preventing buffer overflow during type array allocation. It also adds bounds checking in the add_type function to avoid memory corruption during stage-1 compilation, enhancing the stability of the type management system.
