Subject: [PATCH] fix: update cpu_get_num_math to common_cpu_get_num_math
 (llama.cpp rename)

Upstream llama.cpp renamed cpu_get_num_math() to common_cpu_get_num_math()
in common/common.h as part of the common_* namespace pass. The function
signature is unchanged. This updates the three call sites in the addon to
use the new name, resolving the compile errors when rebuilding against
current llama.cpp.
