SDK v7.1.0

@neurosity/sdk v7.1.0

New Features

Recording API

• neurosity.record({ label, duration }) — one-line fixed-duration brainwave recording
• neurosity.startRecording({ label, maxDuration }) — reactive recording handle with:
  • elapsed$ — Observable of elapsed ms (~1Hz) for progress UI
  • stop() — complete and save the recording
  • cancel() — discard without saving
  • result — Promise that resolves when recording ends
• Recordings are resilient to network outages (saved locally, auto-uploaded on reconnect)

• Type aligned with @neurosity/metrics package (includes standardDeviation, spectrumSlope, status)
