test: add proper test coverage for parseAndSetStructuredOutputs

Fixed test coverage gap where tests were only parsing JSON manually
without actually invoking the parseAndSetStructuredOutputs function.

Changes:
- Export parseAndSetStructuredOutputs for testing
- Rewrite tests to use spyOn() to mock @actions/core functions
- Add tests that actually call the function and verify:
  - core.setOutput() called with correct JSON string
  - core.info() called with correct field count
  - Error thrown when result exists but structured_output undefined
  - Error thrown when no result message exists
  - Handles special characters in field names (hyphens, dots, @ symbols)
  - Handles arrays and nested objects correctly
  - File errors propagate correctly

All 8 tests now properly test the actual implementation with full
coverage of success and error paths.
