test(lint): de-flake lazy-deps in-process gate test — explicit 30s timeout

The in-process variant cold-loads sucrase + typescript and took 5.6s on a
loaded CI runner, tripping vitest's default 5s per-test timeout (Test Core
failure on this PR's first run). The test asserts a loading CONTRACT, not
latency — give it an explicit generous timeout like the sibling dist-based
variants effectively have via their spawn overhead.
