fix(deps): align @vitest/coverage-v8 to 4.1.0 and fix vite peer dep conflict

- Update @vitest/coverage-v8 lockfile entry from 4.0.18 to 4.1.0 to match vitest@4.1.0
- Fix vite peer dep: merge '^8.0.0-0' range into existing vite@7.3.1 lockfile entry
  (avoids yarn classic hoisting conflict that caused install failure)
- Add testTimeout: 10000 to vitest config for slow CI environment
