Rename indri-services-check to services-check (#103)

## Summary
- Rename `indri-services-check` task to `services-check` since it checks all services (indri native, Kubernetes, HTTP endpoints), not just indri-specific ones
- Update references in CLAUDE.md, ai-assistance-guide.md, and troubleshooting.md

## Deployment and Testing
- [ ] Run `mise run services-check` to verify the task works under its new name
