Add nil checks in setSingleImpl() and traversal loop to handle nil
intermediate values gracefully. Per RFC 6901 Section 7, implementations
must raise error conditions for unresolvable paths instead of panicking.

- Add isNil() check before reflection operations in setSingleImpl()
- Add nil validation in set() method traversal loop
- Return descriptive errors: "cannot set field X on nil value"
- Add comprehensive test cases for nil traversal scenarios

Fixes panic: "reflect: call of reflect.Value.Type on zero Value" when
traversing JSON paths containing nil intermediate values.
