fix(deps): pin rolldown to 1.0.2 (1.0.3 breaks oxc transform on macOS CI)

rolldown 1.0.3's darwin/arm64 oxc transform truncates some source files ("Expected } but found EOF"), failing the macOS unit tests. Pin rolldown to 1.0.2 and hold vite at 8.0.14 (which pairs with it) until upstream ships a fix.
