Clarifies that property-based testing should not replace example-based testing entirely.

Changes

Added a "Don't" guideline in the javascript-testing-expert skill file:

**❌ Don't** try to test 100% of the algorithm cases using property-based testing
Why? Property-based testing and example-based testing are complementary. Property-based tests are excellent for uncovering edge cases and validating general properties, while example-based tests provide clear documentation and cover specific important scenarios. Use both approaches together for comprehensive test coverage.

Positioned after the guideline about using property-based testing for edge case detection, reinforcing that both approaches serve distinct purposes in a comprehensive test suite.

Original prompt

in our existing skill add a note with a don't to explain that we should not try to test 100% of the cases of Algo using property based and example based is complementary
