fix: add explicit test timeouts for CLI subprocess E2E tests

CLI subprocess tests (Setup Journey, Doctor Command, Parallel Import)
spawn `bun run src/cli.ts` which takes several seconds to JIT compile +
connect. The Bun test framework default 5000ms per-test timeout is too
tight for CI. Added 30-60s timeouts matching each subprocess's own
timeout to prevent false failures.
