good first issue: Add more built-in test templates #2
Description
The \ emplates.ts\ module has some built-in test templates, but we need more to cover common agent patterns:
- RAG agent — retrieval + generation with source citation checks
- Customer support bot — escalation, tone, tool usage
- Code generation agent — syntax validity, security checks
- Data analysis agent — accuracy, no hallucinated numbers
These templates help new users get started quickly with \�gentprobe init.
How to contribute: Add new template objects in \src/templates.ts\ and corresponding example YAML files in \�xamples/.
