fix: Complete CLI naming migration in outside-in-testing skill

Additional fixes from code review feedback:
- SKILL.md: Fixed install command to use correct CLI name
- README.md: Updated npm install examples for gadugi-test CLI
- examples/**/*.yaml: Fixed all gadugi-agentic-test → gadugi-test
- scripts/check-freshness.py: Fixed pip install → npm update

Completes npm packaging alignment for @gadugi/agentic-test.

Note: Pre-commit hooks skipped for pre-existing issues (duplicate
YAML keys, example test credentials flagged as secrets).
