Mirage Graph Coverage

Read-only coverage auditor for the mirage / MPK persistent-megakernel's GENERATED task graph: cross-references DECLARED tensors (all_tensors[...] in kernel_N.cu) against tensors CONSUMED by tasks (inputs/outputs base_ptr in task_graph_N.json) and flags any tensor declared but never consumed as an input - the "feature defined in code but never wired into the task graph" bug class (e.g. RoPE cos/sin tables allocated but consumed by 0 tasks => position-blind attention => incoherent / degenerate-repetition output). A numerics / relL2 harness silently PASSES on this class, so run THIS first when a megakernel compiles + exits 0 but emits incoherent output. Distinct from inference-graph-diff (vLLM FX / Inductor graphs). Triggers on "graph coverage", "task graph audit", "megakernel wiring", "declared but unconsumed tensor", "rope not wired", "missing task", or "megakernel / mirage / MPK / task-graph" with "coverage / wiring / unconsumed / unwired / audit".
