    hcreate(3): fix incorrect claim that hdestroy frees keys
    
    The man page incorrectly stated that hdestroy() calls free(3) for
    each comparison key. The implementation (hdestroy_r.c) only frees
    the internal table structure, not the user-provided keys or data.
    This matches POSIX, which says hdestroy "shall dispose of the
    search table" without mentioning key deallocation.
    
    Update the description to clarify that the caller is responsible
    for freeing any memory associated with table entries.
