v0.1.0 — first release.

A terminal that shows how much market-data latency costs a strategy, measured on real Manifest order books recorded from two independent RPC channels. Run screen: five delay levels, "delay → P&L" and the cost of 100 ms; Terminal: live book with measured channel lag, data age and staleness; Compare: two real channels side by side, an emulated lane only on a typed profile and always labelled as such. Runs over incomplete data refuse and name the gap; every run is byte-for-byte reproducible. Nothing is sent to any market.
