fix: TooManyTypes test OOMs under -Dpreset=stress's 512-object cap

The pre-push hook's -Dpreset=stress lane (256KB heap, max_objects=512)
caught what the earlier -Dpreset=1m verification couldn't: declaring
1025 type objects hit OutOfMemory well before the TooManyTypes=1024
ceiling this test targets. Gives this one test an explicit, generous
heap/object budget via initWithConfig directly instead of setup()'s
ambient preset-derived limits.
