Bob Nystrom 8fa4f9c1bb refactor: change wrenStringFind to return UINT32_MAX instead of haystack->length for not-found ...

The wrenStringFind function previously returned the haystack length to indicate
a missing needle, which was ambiguous when the needle could legitimately appear
at the end of the string. This commit changes the sentinel value to UINT32_MAX,
updates all callers (string_contains, string_indexOf) to check against the new
sentinel, and adds explicit handling for empty needle and empty haystack edge
cases. The Boyer-Moore-Horspool implementation is also cleaned up with clearer
variable names and comments.
