Fix Codacy warning: replace <climits>/CHAR_BIT with std::numeric_limits

Remove `#include <climits>` which Cppcheck flagged as "Include file not found"
in Codacy Static Code Analysis. Replace `CHAR_BIT` with
`std::numeric_limits<unsigned char>::digits` from `<limits>` (already included),
which is semantically equivalent and avoids the missing-include warning.
