fix(check): do not treat lint warnings as errors in exit code (#1268)

When oxlint reports only warnings (0 errors), override the raw exit code
to SUCCESS instead of propagating oxlint's non-zero exit code. This
fixes ecosystem-ci failures where type-aware lint rules (e.g.
typescript-eslint/await-thenable) produce warnings that cause
`vp check --fix` to exit with code 1.
