fix(recipe): write determinism env vars inline in H100 and perf recipes

The recipe-environment tests parse each builder's env_vars dict with ast and
only accept the COMMON_*_ENV_VARS spread plus literal entries. Spreading
DETERMINISM_ENV_VARS in the Moonlight H100 and DSv3 GB300 perf recipes failed
test_explicit_recipe_environment_invariants and
test_every_flat_recipe_builder_declares_its_environment_inline.
