Currently, ToSliceE(i any) only accepts []any and []map[string]any. Passing concrete slices (such as []string, []int, []bool) or arrays ([N]T) results in an error:
unable to cast []string of type []string to []interface {}

Meanwhile, typed slice functions like ToStringSliceE, ToIntSliceE, etc. support all generic slices and arrays via reflection.
This PR:

1. Adds reflect.Slice and reflect.Array handling in ToSliceE so that any slice or array is safely converted to []any.
2. Uses slices.Clone for []any, resolving the existing // TODO: use slices.Clone.
3. Adds comprehensive unit test cases in TestSlice covering []string, []int, []bool, [2]string, and [2]int.
