fix(executor): 🚨 fix biome formatting in loader test files (#221)

## Summary

Fix 3 biome formatting violations in executor test files introduced by
#219 that weren't caught before merge, causing CI lint failure on main.

## Highlights

- `loader-json-hint.integration.test.ts`: array join wrapping
reformatted
- `loader.test.ts`: expect call wrapping collapsed to single line

## Test plan

- [x] `task lint` passes locally
- [ ] CI green
