Compile trace ledger

Separate graph breaks, compile events, cache hits, eager islands, and guard churn. The frozen trace is intentionally small enough to audit by hand.

Schema: scenarios → baseline/candidate → calls. Each call has phase, duration_ms, graph_ids, breaks, eager_ms, cache, and guard_misses.

Truth boundary: this tool audits imported trace arithmetic. It does not run torch.compile, profile a GPU, or predict production speedup.
