noise-emulate

Emulate a neutral-atom Pulser sequence's time evolution under the target Rydberg device's live noise model, producing noiseless and noisy trajectory curves with a quantile envelope. Asks where to run — this machine, a GPU cluster, or Pasqal Cloud emulators. Use this to study how noise shapes a signal over time; use validate-emu to decide whether an experiment is worth submitting. Triggered by phrases like "run a noise emulation of this sequence", "emu-mps with noise", "noise envelope".
