Some dev machine (e.g. gpu laptop) has low VRAM which causes some tritonbench inputs to OOM. This PR adds HELION_DEV_LOW_VRAM env var and uses smaller inputs if the env var is set. User can choose to opt into this mode by setting the env var, instead of passively having smaller inputs due to low VRAM. stack-info: PR: #325, branch: yf225/stack/31
Fixes issue where variables defined in outer loop scopes were not accessible in subsequent inner loops within the same outer loop iteration. This pattern is common in multi-pass algorithms like layernorm. stack-info: PR: #326, branch: yf225/stack/32
